The cement mixing test shall be waived for this emulsion. The polymer material shall be milled or blended into the asphalt or emulsifier solution prior to the emulsification process. The minimum amount and type of polymer modifier shall be determined by the laboratory performing the mix design. The minimum amount required will be based on asphalt weight content and will be certified by the emulsion supplier. In general, a three percent (3%) polymer solids, based on asphalt weight, is considered minimum. The five-day (5) settlement test may be waived, provided job stored emulsion is used within thirty-six (36) hours from the time of the shipment, or the stored material has had additional emulsion blended into it prior to use. Each load of emulsified asphalt shall be accompanied with a Certificate of Analysis/Compliance to assure that it is the same as that used in the mix design. For 42 Pavement Management Alternative Methods Bid No. 15-601 the first load of emulsified asphalt produced for the project, the supplier shall submit a application, the owner / buying agency may sample and test all subsequent loads of emulsified asphalt delivered to the project to verify and determine compliance with specification requirements. Where these tests identify material outside specification requirements, the owner may require the supplier to cease shipment of that pretested emulsified asphalt product. Further shipment of that pretested emulsified asphalt problem is evaluated and corrected by the supplier as necessary to the satisfaction of the owning agency. C. Aggregate: The mineral aggregate used shall be of the type and grade specified for the particular use of the Microsurfacing. The aggregate shall be a manufactured crushed stone such as granite, slag, limestone, chat, or other high-quality aggregate, or combination thereof. To assure the material is totally crushed, one-hundred percent (100%) of the parent aggregate will be larger than the largest stone in the gradation to be used. When aggregate is tested according to the following test, it should meet these minimum requirements: AASHTO ASTM QUALITY SPECIFICATION TEST NO. TEST NO. T176 D2419 Sand Equivalent 65 Minimum T104 C88 Soundness 15% Maximum using NA2 SO4 or 25% Maximum using MgSO4 T96 C131 Abrasion Resistance 30% Maximum The abrasion test is to be run on the parent aggregate. The aggregate should meet state-approved polishing values. Proven performance may justify the use of aggregates that may not pass all of the above tests. When tested in accordance with AASHTO T27 (ASTM C136) and AASHTO T11 (ASTM C117), the target (mix design) aggregate gradation (including the mineral filler) shall be within one of the following bands. SIEVE SIZE TYPE II TYPE III STOCKPILE % PASSING % PASSING TOLERANCE 100 100 #4 (4.75 mm) 90 100 70 - 90 ± 5 % #8 (2.36 mm) 65 90 45 70 ± 5 % #16 (1.18 mm) 45 70 28 - 50 ± 5 % #30 (600 um) 30 50 19 - 34 ± 5 % #50 (330 um) 18 30 12 - 25 ± 4 % #100 (150 um) 10 21 7 - 18 ± 3 % #200 (75 um) 5 15 5 - 15 ± 2 % The job mix (target) gradation shall be within the gradation band for the desired type. After the target gradation has been submitted (this should be the gradation that the mix design is based on), then the percent passing each sieve shall not vary by more than the stockpile tolerance shown in the above table for each individual sieve, and still 43 Pavement Management Alternative Methods Bid No. 15-601 remain within the gradation band. It is recommended that the percent passing shall not go from the high end to the low end of the range for any two consecutive screens. The aggregate will be accepted at the job location stockpile or when loading into the support units for delivery to the lay-down machine. The stockpile shall be accepted based on five gradation tests according to AASHTO T2 (ASTM D75). If the average of the five tests is within the gradation tolerances, then the materials will be accepted. If the tests show the material to be out, the contractor will be given the choice to either remove the material or blend other aggregate with the stockpiled material to bring it into specification. Materials used in blending must meet the quality tests before blending and must be blended in a manner to produce a consistent gradation. If blending is used, it will require that a new mix design be performed. The contractor shall supply copies of the aggregate tickets to the customer within 24 hours of delivery to the job site. Screening shall be required at the stockpile prior to delivery to the paving machine if there are any problems created by having oversize material in the mix. D. Mineral filler: (if required) shall be any recognized brand of non-air entrained Portland cement or hydrated lime that is free from lumps. It may be accepted upon visual inspection. The type and amount of mineral filler needed shall be determined by a laboratory mix design and will be considered as part of the aggregate gradation. An increase or decrease of less than one percent (1%) may be permitted when the Microsurfacing is being placed if it is found to be necessary for better consistency or set times. E. Water: Potable and free of harmful or deleterious materials. F. Additives: Additives may be added to the emulsion mix or any of the component materials to provide the control of the quick-traffic properties. They must be included as part of the mix design and be compatible with the other components of the mix. III. Mix Design: The Contractor shall submit to the County for approval a complete mix design with an aggregate source used on five (5) similar micro surfacing projects. The mix design shall be prepared and certified by a laboratory which has experience in designing Microsurfacing. After the mix design has been approved, no substitution will be permitted, unless approved by the County. Compatibility of the aggregate, polymer-modified emulsion, mineral filler, and other additives shall be verified by the mix design. The mix design shall be made with the same aggregate gradation that the contractor will provide on the project. Recommended tests and values are as follows: 44 Pavement Management Alternative Methods Bid No. 15-601 ISSA TEST DESCRIPTION SPECIFICATION NO.

The purpose of this test is to determine the minimum asphalt content of a micro surface system. The Wet Track Abrasion Test is not recommended as a field quality control or acceptance test. Some systems require longer times for the asphalt to adhere to the stone. In these systems, a modified Marshall Stability Test (ISSA TB-148) or Hveem Cohesiometer Test (ASTM D 1560) has been used to confirm asphalt content. ISSA DESCRIPTION SPECIFICATION TEST NO.

It is more for information to be used by the contractor than for quality of the end product. The mixing test and set-time test should be checked at the highest temperatures expected during construction. The mix design should report the quantitative effects of moisture content on the unit weight of the aggregate (bulking effect). The report must clearly show the proportions of aggregate, mineral filler (minimum and maximum), water (minimum and maximum), additive usage, and polymer-modified asphalt emulsion based on the dry weight of the aggregate. All the component materials used in the mix design shall be representative of the materials proposed by the contractor to be used on the project. The percentages of each individual material required shall be shown in the laboratory report. Adjustments may be required during construction, based on field conditions. The Project Manager will give final approval for all such adjustments.

The mixture shall not be applied when weather conditions prolong opening to traffic beyond a reasonable time or as directed by the County. C. Site and Surface Preparation: The first step of surface preparation is to restore the 47 Pavement Management Alternative Methods Bid No. 15-601 patching and crack sealing. All pavement marking shall be removed, maintained, and compensated for in accordance to FDOT Standard Specification Section 102-5.8. Immediately prior to applying the Microsurfacing, the surface shall be cleared of all loose material, silt spots, vegetation, and other objectionable material. The Contractor shall be responsible for clipping back shoulders and removing overburden or any other vegetation or debris to ensure that the road is free of organic and deleterious material. Any standard cleaning method will be acceptable. If water is used, cracks shall be allowed to dry thoroughly before applying Microsurfacing. Manholes, valve boxes, drop inlets and other service entrances shall be protected from the Microsurfacing by a suitable method. Utility inlets should be covered with heavy paper or roofing felt adhered to the surface of the inlet. The paper is removed once the micro-surfacing has sufficiently cured. In addition to covering the inlets, all starts, stops, and handwork on turnouts should be done on roofing felt to ensure sharp, uniform joints and edges. The County shall approve the surface preparation prior to surfacing. No dry aggregate either spilled from the lay-down machine or existing on the road, will be permitted. D. Tack Coat: Normally, tack coat is not required unless the surface to be covered is extremely dry and raveled or is concrete or brick. If required, the tack coat should consist of one part emulsified asphalt/three parts water and should be applied with a standard distributor. The emulsified asphalt should be SS or CSS grade. The distributor shall be capable of applying the dilution evenly at a rate of 0.05 to 0.10 gal/yd² (0.23 to 0.45 l/m²). The tack coat shall be allowed to cure sufficiently before the application of Microsurfacing. If a tack coat is to be required, it must be billed as a separate pay item. E.

The Microsurfacing shall be of the desired consistency upon leaving the mixer. A sufficient amount of material shall be carried in all parts of the spreader at all times so that a complete coverage is obtained. Overloading of the spreader shall be avoided. No lumping, balling, or unmixed aggregate shall be permitted. No streaks, such as those caused by oversized aggregate, shall be left in the finished surface. If excess streaking develops, the job will be stopped until the contractor proves to the Project Manager or his/her designee that the situation has been corrected. Excessive streaking is defined as more than four drag marks greater than one-half (½) inch wide (12.7 mm) and four inches (4) long (101 mm), or one inch (1) wide (25.4 mm) and three (3) inches long (76.2 mm), in any 29.9 yd² (25 m²) area. No transverse ripples or longitudinal streaks of one-fourth (¼) inch in depth (6.4 m²) will be permitted, when measured by placing a ten (10) foot (3 m) straight edge over the surface. 48 Pavement Management Alternative Methods Bid No. 15-601 The Microsurfacing mixture shall be of the proper consistency at all times, so as to provide the application rate required by the surface condition. The average single application rate, as measured by the Project Manager, shall be in accordance with the following table: SUGGESTED AGGREGATE TYPE LOCATION APPLICATION RATES TYPE II Urban and Residential Streets 20 - 24 lb/yd² (+/- 2 lbs) Single application TYPE II Urban, Residential, and Primary Routes 30 - 34 lb/yd² (+/- 2 lbs) Double application TYPE II Primary and Cold Mix Roads as 24 - 28 lb/yd² (+/- 2 lbs) Heavy single application directed TYPE II Primary and Cold Mix Roads as Heavy double 38 42 lb/ yd² (+/- 2 lbs) directed application TYPE II Rut Fill Wheel Ruts Tonnage As Required Suggested application rates are based upon the weight of dry aggregate in the mixture. Application rates are affected by the unit weight of the aggregate. Microsurfacing is often put down in two full-width passes in place of rut-filling when the rutting or deformation is not severe. When two passes are used, the first pass (scratch course) is made using a metal or stiff rubber strike-off and applying only what the surface demands for leveling. The second course is applied at 15 30 lb/yd² (8.1 16.3 kg/m²). F. Joints: No excess buildup, uncovered areas, or unsightly appearance shall be permitted on longitudinal or transverse joints. The contractor shall provide suitable-width spreading equipment to produce a minimum number of longitudinal joints throughout the project.

The projects will then be done on a work order basis. Question 8. Must the bidders bid on all treatment or can they bid on specific treatments? Answer: Each alternative treatment will have a separate bid sheet. The bidders may bid on any one of the alternative treatments, but must bid on every line item Question 9.

Answer: PC-001 refers to milling of existing asphalt pavement, and shall be done in accordance with FDOT Standard Specification Section 327. Question 12. Does the County have any history or records of documented performance for any of these treatments? Answer: The County has had limited experience in the past with alternate pavement preservation treatments, mostly Hot-in-Place. The County can provide some information on those, if necessary. However, in essence this will be the first formal incursion into this area of pavement preservation, and considered a pilot program for this first year. Question 13. In regards to line item 337-1 for the Full Depth Reclamation and Cold-in- Place, is the indication of a PG for the ARB referring to an older FDOT specification? Page 4 ADDENDUM #3 BID#15-601 Pavement Management Alternative Methods Answer: This line item has been revised to reflect the current FDOT standard. Question 14.

Answer: RAP may be added as part of the homogeneous mixed material that will form the widened area. Question 16. Will the work orders be independent streets or groups of streets? Answer: With the exception of the asphalt recycling treatments, which are more appropriate for single long road stretches, the roads will be grouped by proximity when possible, such as in the case of subdivisions. Question 17. Will the funding for these projects be from carried over funds or the next fiscal year? Answer: These projects will be funded from the FY15-16 budget which starts on st October 1. Question 18. submit 3 maintenance projects for each alternative method bid upon, of the work exceeded $50,000.00. The projects must be for FDOT or for local qualified bidders due to the fact that the FDOT does not contract this type of work. Very few government agencies contract this type of work as well. Since so little of this type of work is contracted by these agencies Polk County will have a very limited number of bidders. Pleas review this prequalification condition. Answer: The condition has been revised to indicate experience in projects exceeding $30K and they may be for any government agency, local or out of state. Question 19. In Category PC-005 Micro-surfacing, Item IX. Warranty, calls for a 3 year warranty, is a maintenance bond required with this? Answer: No maintenance bond will be required. Question 20. Can a list of streets be given to us for each method? If we do not have a list of streets then the pricing for Maintenance of Traffic, Testing and Daily Production will be a guess and the pricing will reflect this. Answer: A list will not be provided at this time. Refer to the answer for Question 7.

The cement mixing test shall be waived for this emulsion. The polymer material shall be milled or blended into the asphalt or emulsifier solution prior to the emulsification process. The minimum amount and type of polymer modifier shall be determined by the laboratory performing the mix design. The minimum amount required will be based on asphalt weight content and will be certified by the emulsion supplier. In general, a three percent (3%) polymer solids, based on asphalt weight, is considered minimum. The five-day (5) settlement test may be waived, provided job stored emulsion is used within thirty-six (36) hours from the time of the shipment, or the stored material has had additional emulsion blended into it prior to use. Each load of emulsified asphalt shall be accompanied with a Certificate of Analysis/Compliance to assure that it is the same as that used in the mix design. For 55 Pavement Management Alternative Methods Bid No. 15-601 the first load of emulsified asphalt produced for the project, the supplier shall submit a application, the owner / buying agency may sample and test all subsequent loads of emulsified asphalt delivered to the project to verify and determine compliance with specification requirements. Where these tests identify material outside specification requirements, the owner may require the supplier to cease shipment of that pretested emulsified asphalt product. Further shipment of that pretested emulsified asphalt problem is evaluated and corrected by the supplier as necessary to the satisfaction of the owning agency. C. Aggregate: The mineral aggregate used shall be of the type and grade specified for the particular use of the Microsurfacing. The aggregate shall be a manufactured crushed stone such as granite, slag, limestone, chat, or other high-quality aggregate, or combination thereof. To assure the material is totally crushed, one-hundred percent (100%) of the parent aggregate will be larger than the largest stone in the gradation to be used. When aggregate is tested according to the following test, it should meet these minimum requirements: AASHTO ASTM QUALITY SPECIFICATION TEST NO.TEST NO.

After the target gradation has been submitted (this should be the gradation that the mix design is based on), then the percent passing each sieve shall not vary by more than the stockpile tolerance shown in the above table for each individual sieve, and still 56 Pavement Management Alternative Methods Bid No. 15-601 remain within the gradation band. It is recommended that the percent passing shall not go from the high end to the low end of the range for any two consecutive screens. The aggregate will be accepted at the job location stockpile or when loading into the support units for delivery to the lay-down machine. The stockpile shall be accepted based on five gradation tests according to AASHTO T2 (ASTM D75). If the average of the five tests is within the gradation tolerances, then the materials will be accepted. If the tests show the material to be out, the contractor will be given the choice to either remove the material or blend other aggregate with the stockpiled material to bring it into specification. Materials used in blending must meet the quality tests before blending and must be blended in a manner to produce a consistent gradation. If blending is used, it will require that a new mix design be performed. The contractor shall supply copies of the aggregate tickets to the customer within 24 hours of delivery to the job site. Screening shall be required at the stockpile prior to delivery to the paving machine if there are any problems created by having oversize material in the mix. D. Mineral filler: (if required) shall be any recognized brand of non-air entrained Portland cement or hydrated lime that is free from lumps. It may be accepted upon visual inspection. The type and amount of mineral filler needed shall be determined by a laboratory mix design and will be considered as part of the aggregate gradation. An increase or decrease of less than one percent (1%) may be permitted when the Microsurfacing is being placed if it is found to be necessary for better consistency or set times. E. Water: Potable and free of harmful or deleterious materials. F. Additives: Additives may be added to the emulsion mix or any of the component materials to provide the control of the quick-traffic properties. They must be included as part of the mix design and be compatible with the other components of the mix. Formatted: Outline numbered + Level: 1 + Numbering Style: I, II, III, + Start at: 1 + III. Mix Design: Alignment: Left + Aligned at: 0" + Indent at: 0" The Contractor shall submit to the County for approval a complete mix design with an aggregate source used on five (5) similar micro surfacing projects.

The purpose of this test is to determine the minimum asphalt content of a micro surface system. The Wet Track Abrasion Test is not recommended as a field quality control or acceptance test. Some systems require longer times for the asphalt to adhere to the stone. In these systems, a modified Marshall Stability Test (ISSA TB-148) or Hveem Cohesiometer Test (ASTM D 1560) has been used to confirm asphalt content. ISSA DESCRIPTION SPECIFICATION TEST NO.

It is more for information to be used by the contractor than for quality of the end product. The mixing test and set-time test should be checked at the highest temperatures expected during construction. The mix design should report the quantitative effects of moisture content on the unit weight of the aggregate (bulking effect). The report must clearly show the proportions of aggregate, mineral filler (minimum and maximum), water (minimum and maximum), additive usage, and polymer-modified asphalt emulsion based on the dry weight of the aggregate. All the component materials used in the mix design shall be representative of the materials proposed by the contractor to be used on the project. The percentages of each individual material required shall be shown in the laboratory report. Adjustments may be required during construction, based on field conditions. The Project Manager will give final approval for all such adjustments.

Traffic shall not travel on fresh mix until rolling and blotting has been completed. The Contractor shall submit an M.O.T plan indication all facets of traffic control for the project area. The MOT plan must be approved in writing by the County prior to commencing any work. All traffic control shall be in accordance with the FDOT Roadway Design Standards, most current edition and TP-102. M.O.T. and associated devices shall be checked daily and periodically throughout the project for compliance; and where adjustments or corrections are needed, prompt revisions shall be made. Traffic shall not be allowed on the roadway after placement of the chip seal for a minimum of two hours. During and after placement of the chip seal, pilot cars should escort traffic at a speed of 20 mph (30 kph) over the chip sealed surface for two to 24 hours. Once all the loose aggregate is removed from the new chip seal surface, pilot cars are no longer needed. F. Application of bituminous material: Liquid bituminous material shall be applied by means of a pressure type distributor in a uniform, continuous spread over the section to be treated. The distributor shall be moving forward at the proper speed when the liquid is discharged onto the pavement to provide an even and consistent application at the rate prescribed. If any areas are deficient the operation shall be stopped and corrected immediately. The liquid shall spreader when the ambient air temperature is above 75 degrees or one hundred below 75 degrees. 41 Pavement Management Alternative Methods Bid No. 15-601 Single Chip Seal: Application of the liquid bituminous material shall be applied at a rate of .38 -.45 gallons per square yard depending on the composition of the existing road bed, surface texture and the size of the aggregate in use. Double Chip Seal: The second application of liquid bituminous material shall be applied at a rate of .38 - .42 gallons per square yard depending upon the size of the first layer of aggregate that the liquid is sprayed upon and the size of the aggregate being placed over the first application of surface treatment. G. Application of cover Aggregate: Immediately following the spray application of the liquid bituminous material, cover aggregate shall be spread over the liquid material at a rate of 18 30 lbs square yard depending upon the type of road base and/or the size of the existing aggregate that is being resurfaced. H. Rolling: Immediately following the first application of the cover material, roll the entire surface with a pneumatic roller, followed immediately with the steel drum roller. Cover the entire surface one time with the steel drum roller. Then, roll the cover material again with the pneumatic roller. Continue rolling as long as necessary to ensure thorough keying of the cover aggregate into the liquid bituminous material. Eliminate the steel drum when rolling the second application of cover aggregate. Apply the second application of liquid and cover material the same day as the first application, as far as it is practicable and consistent with the setting of the liquid bituminous material. I. Sweeping: After rolling of the first application of cover aggregate, lightly broom the loose aggregate in a manner not to dislodge the aggregate embedded in the liquid. Sweep loose material from road bed. Following second application again broom loose aggregate from the road bed prior to the application of the fog seal. If temperatures exceed 85 degrees, it may be necessary to wait 24 hours before sweeping the first application of chip seal. J. Fog Seal: Upon direction from the Engineer, fog seal is to be applied as a separate pay item. When surface treatment has set, a fog seal is to be applied at a rate of .1 to .15 gallons per square yard to the entire surface treatment. The liquid for fog seal shall be a cationic mixing type emulsion diluted forty (40%) percent with water. Fog seal shall then be lightly sanded at a rate of plus or minus two (2) pounds per square yard by means of a mechanical spreader. VI. General Performance: Provide completed pavement which performs to the satisfaction of the engineer without bleeding, rutting, shoving, raveling, stripping, or showing other types of pavement distress or unsatisfactory performance.

Microsurfacing is a polymer-modified cold-mix paving system that begins as a mixture of dense-graded aggregate, polymer modified asphalt emulsion, water, and mineral fillers placed in a slurry state at ambient air temperature to extend the service life of both urban and rural roads within the County. The end product should maintain a skid-resistant surface in variable thick sections throughout the service life of the micro surfacing. II. Materials: A. Emulsified Asphalt: Provide quick-traffic latex modified cationic type CSS emulsion with natural or synthetic latex conforming to the requirements specified in AASHTO M208 or ASTM D2397 for CSS-1H.

The cement mixing test shall be waived for this emulsion. The polymer material shall be milled or blended into the asphalt or emulsifier solution prior to the emulsification process. The minimum amount and type of polymer modifier shall be determined by the laboratory performing the mix design. The minimum amount required will be based on asphalt weight content and will be certified by the emulsion supplier. In general, a three percent (3%) polymer solids, based on asphalt weight, is considered minimum. The five-day (5) settlement test may be waived, provided job stored emulsion is used within thirty-six (36) hours from the time of the shipment, or the stored material has had additional emulsion blended into it prior to use. Each load of emulsified asphalt shall be accompanied with a Certificate of Analysis/Compliance to assure that it is the same as that used in the mix design. For 44 Pavement Management Alternative Methods Bid No. 15-601 the first load of emulsified asphalt produced for the project, the supplier shall submit a application, the owner / buying agency may sample and test all subsequent loads of emulsified asphalt delivered to the project to verify and determine compliance with specification requirements. Where these tests identify material outside specification requirements, the owner may require the supplier to cease shipment of that pretested emulsified asphalt product. Further shipment of that pretested emulsified asphalt problem is evaluated and corrected by the supplier as necessary to the satisfaction of the owning agency. C. Aggregate: The mineral aggregate used shall be of the type and grade specified for the particular use of the Microsurfacing. The aggregate shall be a manufactured crushed stone such as granite, slag, limestone, chat, or other high-quality aggregate, or combination thereof. To assure the material is totally crushed, one-hundred percent (100%) of the parent aggregate will be larger than the largest stone in the gradation to be used. When aggregate is tested according to the following test, it should meet these minimum requirements: AASHTO ASTM QUALITY SPECIFICATION TEST NO. TEST NO. T176 D2419 Sand Equivalent 65 Minimum T104 C88 Soundness 15% Maximum using NA2 SO4 or 25% Maximum using MgSO4 T96 C131 Abrasion Resistance 30% Maximum The abrasion test is to be run on the parent aggregate. The aggregate should meet state-approved polishing values. Proven performance may justify the use of aggregates that may not pass all of the above tests. When tested in accordance with AASHTO T27 (ASTM C136) and AASHTO T11 (ASTM C117), the target (mix design) aggregate gradation (including the mineral filler) shall be within one of the following bands. SIEVE SIZE TYPE II TYPE III STOCKPILE % PASSING % PASSING TOLERANCE 100 100 #4 (4.75 mm) 90 100 70 - 90 ± 5 % #8 (2.36 mm) 65 90 45 70 ± 5 % #16 (1.18 mm) 45 70 28 - 50 ± 5 % #30 (600 um) 30 50 19 - 34 ± 5 % #50 (330 um) 18 30 12 - 25 ± 4 % #100 (150 um) 10 21 7 - 18 ± 3 % #200 (75 um) 5 15 5 - 15 ± 2 % The job mix (target) gradation shall be within the gradation band for the desired type. After the target gradation has been submitted (this should be the gradation that the mix design is based on), then the percent passing each sieve shall not vary by more than the stockpile tolerance shown in the above table for each individual sieve, and still 45 Pavement Management Alternative Methods Bid No. 15-601 remain within the gradation band. It is recommended that the percent passing shall not go from the high end to the low end of the range for any two consecutive screens. The aggregate will be accepted at the job location stockpile or when loading into the support units for delivery to the lay-down machine. The stockpile shall be accepted based on five gradation tests according to AASHTO T2 (ASTM D75). If the average of the five tests is within the gradation tolerances, then the materials will be accepted. If the tests show the material to be out, the contractor will be given the choice to either remove the material or blend other aggregate with the stockpiled material to bring it into specification. Materials used in blending must meet the quality tests before blending and must be blended in a manner to produce a consistent gradation. If blending is used, it will require that a new mix design be performed. The contractor shall supply copies of the aggregate tickets to the customer within 24 hours of delivery to the job site. Screening shall be required at the stockpile prior to delivery to the paving machine if there are any problems created by having oversize material in the mix. D. Mineral filler: (if required) shall be any recognized brand of non-air entrained Portland cement or hydrated lime that is free from lumps. It may be accepted upon visual inspection. The type and amount of mineral filler needed shall be determined by a laboratory mix design and will be considered as part of the aggregate gradation. An increase or decrease of less than one percent (1%) may be permitted when the Microsurfacing is being placed if it is found to be necessary for better consistency or set times. E. Water: Potable and free of harmful or deleterious materials. F. Additives: Additives may be added to the emulsion mix or any of the component materials to provide the control of the quick-traffic properties. They must be included as part of the mix design and be compatible with the other components of the mix. III. Mix Design: The Contractor shall submit to the County for approval a complete mix design with an aggregate source used on five (5) similar micro surfacing projects. The mix design shall be prepared and certified by a laboratory which has experience in designing Microsurfacing. After the mix design has been approved, no substitution will be permitted, unless approved by the County. Compatibility of the aggregate, polymer-modified emulsion, mineral filler, and other additives shall be verified by the mix design. The mix design shall be made with the same aggregate gradation that the contractor will provide on the project. Recommended tests and values are as follows: 46 Pavement Management Alternative Methods Bid No. 15-601 ISSA TEST DESCRIPTION SPECIFICATION NO.

The purpose of this test is to determine the minimum asphalt content of a micro surface system. The Wet Track Abrasion Test is not recommended as a field quality control or acceptance test. Some systems require longer times for the asphalt to adhere to the stone. In these systems, a modified Marshall Stability Test (ISSA TB-148) or Hveem Cohesiometer Test (ASTM D 1560) has been used to confirm asphalt content. ISSA DESCRIPTION SPECIFICATION TEST NO.

It is more for information to be used by the contractor than for quality of the end product. The mixing test and set-time test should be checked at the highest temperatures expected during construction. The mix design should report the quantitative effects of moisture content on the unit weight of the aggregate (bulking effect). The report must clearly show the proportions of aggregate, mineral filler (minimum and maximum), water (minimum and maximum), additive usage, and polymer-modified asphalt emulsion based on the dry weight of the aggregate. All the component materials used in the mix design shall be representative of the materials proposed by the contractor to be used on the project. The percentages of each individual material required shall be shown in the laboratory report. Adjustments may be required during construction, based on field conditions. The Project Manager will give final approval for all such adjustments. COMPONENT MATERIALS LIMITS Residual Asphalt 7% to 10.5% by dry weight of aggregate Mineral Filler 0.0 to 3% by dry weight of aggregate Polymer-Based Modifier Minimum of 3% solids based on bitumen weight content Additives As needed Water As required to produce proper mix consistency 47 Pavement Management Alternative Methods Bid No. 15-601 IV. Sampling and Testing: The Engineer at their discretion shall obtain two samples of micro surfacing mixture for each day of production. The samples shall be obtained at different periods during the production day and the Engineer shall test each sample at the expense of the County in accordance with FM 5-563 and FM 1-T 030 to determine the residual asphalt content and the gradation of each sample. Evaporate all water from the sample prior to testing. V. EXPERIENCE: All contractors and their subcontractors shall be FDOT prequalified. Bidders must submit a minimum of five Micro Surfacing project references that have been completed within the past three years. Bidders may be required to submit detailed information regarding the staff that they propose for this project.

Mixing Equipment: The machine shall be specifically designed and manufactured to lay Microsurfacing. The material shall be mixed by an automatic-sequenced, self- propelled Microsurfacing mixing machine, which shall be a continuous-flow mixing unit able to accurately deliver and proportion the aggregate, emulsified asphalt, mineral filler, control setting additive, and water to a revolving multi-blade, double-shafted mixer and to discharge the mixed product on a continuous-flow basis. The machine shall have sufficient storage capacity for aggregate, emulsified asphalt, mineral filler, control additive and water to maintain an adequate supply to the proportioning controls. The machine shall be equipped to allow the operator to have full control, from the rear of the machine, of the forward and reverse speeds during applications of the Microsurfacing material and be equipped with opposite-side driver stations to assist in alignment. The self-loading device, opposite-side driver stations, and forward and reverse speed controls shall be original equipment manufacturer design. B. Proportioning Devices: Individual volume or weight controls for proportioning each material to be added to the mix (i.e. aggregate, mineral filler, emulsified asphalt, additive, and water) shall be provided and properly marked. These proportioning devices are used in material calibration and determining the material output at any time. C. Spreading Device: The mixture shall be agitated and spread uniformly in the surfacing box by means of twin-shafted paddles or spiral augers fixed in the spreader box. A front seal shall be provided to insure no loss of the mixture at the road contact point. The rear seal shall act as a final strike-off and shall be adjustable. The spreader box and rear strike-off shall be so designed and operated that a uniform consistency is achieved to produce a free flow of material to the rear strike-off. The spreader box shall have suitable means provided to side shift the box to compensate for variations in the pavement geometry. 48 Pavement Management Alternative Methods Bid No. 15-601 D. Secondary Strike-off: A secondary strike-off shall be provided to improve surface texture. The secondary strike-off shall have the same adjustments as the spreader box. No burlap drags will be permitted on the final applications. E. Rut-Filling Box: When required, before the final surface course is placed, preliminary Microsurfacing material may be required to fill ruts, utility cuts, depressions in the existing surface, etc. Ruts of one-half (½) inch (12.7 mm) or greater in depth shall be filled independently with a rut-filling spreader box, either five foot (5) (1.5m) or six foot (6) (1.8 m) in width. For irregular or shallow rutting of less than one-half (½) inch (12.7 mm) in depth, a full-width scratch-coat pass may be used as directed by the County. Ruts that are in excess of one and one-half (1-½) inches (38.1 mm) in depth may require multiple placements with the rut-filling spreader box to restore the cross-section. All rut-filling level-up material should cure under traffic for at least a twenty-four (24) hour period before additional material is placed on top of the level-up. F. Auxiliary Equipment: Suitable surface preparation equipment, traffic control equipment, hand tools, and any other support and safety equipment shall be provided by the contractor as necessary, (or as the County requires) to perform the work. G. General: Each mixing unit to be used in the performance of the work shall be calibrated in the presence of the County prior to construction. Previous calibration documentation covering the exact materials to be used may be acceptable, provided that no more than sixty (60) days have lapsed. The documentation shall include an individual calibration of each material at various settings, which can be related to the machine metering devices. No machine will be allowed to work on the project until the calibration has been completed and/or accepted. All equipment, tools, and machines used in the performance of this work shall be maintained in satisfactory working condition at all times to ensure a high-quality product. Availability of quality assurance devices (such as a 15' straight edge) shall be the responsibility of the Contractor. VII. Construction: A. Test Strip: A test strip 1000 feet long and the width of one lane shall be provided. The test must include all courses specified and must be constructed at the same time of day as the scheduled full scale production. The test strip will be evaluated for 24 hours after placement and will be subject to approval from the engineer before any further production. If unsatisfactory, the test strip shall be removed and another strip placed for B. Weather Limitations: Microsurfacing shall not be applied if either the pavement or air temperature is below 50°F (10°C) and falling, but may be applied when both pavement and air temperatures are above 45°F (7°C) and rising. No Microsurfacing shall be applied when there is the possibility that the finished product will freeze within 24 hours. The mixture shall not be applied when weather conditions prolong opening to traffic beyond a reasonable time or as directed by the County. 49 Pavement Management Alternative Methods Bid No. 15-601 C. Field Verification It is understood that all treatment activities will take place within the paved roadway surface. Prior to beginning work, the Contractor shall carefully examine the site of work treatment and construction activities are confined to the paved roadway, taking the necessary precautions to protect the areas outside of the edge of pavement during construction from damages or contamination. Should the construction activities or application of the surface treatment cause damages to the adjoining properties outside of the edge of pavement, the Contractor shall be responsible for restoring these areas to their original condition or better, at their expense. D. Site and Surface Preparation: The first step of surface preparation is to restore the patching and crack sealing. All pavement marking shall be removed, maintained, and compensated for in accordance to FDOT Standard Specification Section 102-5.8. Immediately prior to applying the Microsurfacing, the surface shall be cleared of all loose material, silt spots, vegetation, and other objectionable material. The Contractor shall be responsible for clipping back shoulders and removing overburden or any other vegetation or debris to ensure that the road is free of organic and deleterious material. Any standard cleaning method will be acceptable. If water is used, cracks shall be allowed to dry thoroughly before applying Microsurfacing. Manholes, valve boxes, drop inlets and other service entrances shall be protected from the Microsurfacing by a suitable method. Utility inlets should be covered with heavy paper or roofing felt adhered to the surface of the inlet. The paper is removed once the micro-surfacing has sufficiently cured. In addition to covering the inlets, all starts, stops, and handwork on turnouts should be done on roofing felt to ensure sharp, uniform joints and edges. The County shall approve the surface preparation prior to surfacing. No dry aggregate either spilled from the lay-down machine or existing on the road, will be permitted. E. Tack Coat: Normally, tack coat is not required unless the surface to be covered is extremely dry and raveled or is concrete or brick. If required, the tack coat should consist of one part emulsified asphalt/three parts water and should be applied with a standard distributor. The emulsified asphalt should be SS or CSS grade. The distributor shall be capable of applying the dilution evenly at a rate of 0.05 to 0.10 gal/yd² (0.23 to 0.45 l/m²). The tack coat shall be allowed to cure sufficiently before the application of Microsurfacing. If a tack coat is to be required, it must be billed as a separate pay item. F. Application: A test strip shall be placed in conditions similar to those expected to be encountered during the project unless specifically waived by the county. When required by local conditions, the surface shall be pre-wetted ahead of the spreader box. The rate of application of the spray shall be adjusted during the day to suit temperatures, surface texture, humidity, and dryness of the pavement. 50 Pavement Management Alternative Methods Bid No. 15-601 The Microsurfacing shall be of the desired consistency upon leaving the mixer. A sufficient amount of material shall be carried in all parts of the spreader at all times so that a complete coverage is obtained. Overloading of the spreader shall be avoided. No lumping, balling, or unmixed aggregate shall be permitted. No streaks, such as those caused by oversized aggregate, shall be left in the finished surface. If excess streaking develops, the job will be stopped until the contractor proves to the Project Manager or his/her designee that the situation has been corrected. Excessive streaking is defined as more than four drag marks greater than one-half (½) inch wide (12.7 mm) and four inches (4) long (101 mm), or one inch (1) wide (25.4 mm) and three (3) inches long (76.2 mm), in any 29.9 yd² (25 m²) area. No transverse ripples or longitudinal streaks of one-fourth (¼) inch in depth (6.4 m²) will be permitted, when measured by placing a ten (10) foot (3 m) straight edge over the surface. The Microsurfacing mixture shall be of the proper consistency at all times, so as to provide the application rate required by the surface condition. The average single application rate, as measured by the Project Manager, shall be in accordance with the following table: SUGGESTED AGGREGATE TYPE LOCATION APPLICATION RATES TYPE II Urban and Residential Streets 20 - 24 lb/yd² (+/- 2 lbs) Single application TYPE II Urban, Residential, and Primary Routes 30 - 34 lb/yd² (+/- 2 lbs) Double application TYPE II Primary and Cold Mix Roads as 24 - 28 lb/yd² (+/- 2 lbs) Heavy single application directed TYPE II Primary and Cold Mix Roads as Heavy double 38 42 lb/ yd² (+/- 2 lbs) directed application TYPE II Rut Fill Wheel Ruts Tonnage As Required Suggested application rates are based upon the weight of dry aggregate in the mixture. Application rates are affected by the unit weight of the aggregate. Microsurfacing is often put down in two full-width passes in place of rut-filling when the rutting or deformation is not severe. When two passes are used, the first pass (scratch course) is made using a metal or stiff rubber strike-off and applying only what the surface demands for leveling. The second course is applied at 15 30 lb/yd² (8.1 16.3 kg/m²). G. Joints: No excess buildup, uncovered areas, or unsightly appearance shall be permitted on longitudinal or transverse joints. The contractor shall provide suitable-width spreading equipment to produce a minimum number of longitudinal joints throughout the project. When possible, longitudinal joints shall be placed on lane lines. Half passes and odd-width passes will be used only in minimum amounts. If half passes are used, they shall not be the last pass of any paved area. A maximum of three (3) inches (76.2 mm) 51 Pavement Management Alternative Methods Bid No. 15-601 shall be allowed for overlap of longitudinal lane line joints. Also, the joint shall have no more than a one-fourth (¼) inch (6.4 mm) difference in elevation when measured by placing a ten (10) foot (3 m) straight edge over the joint and measuring the elevation drop-off. H. Mix Stability: The Microsurfacing shall possess sufficient stability so that premature breaking of the material in the spreader box does not occur. The mixture shall be homogeneous during and following mixing and spreading. It shall be free of excess water or emulsion and free of segregation of the emulsion and aggregate fines from the coarser aggregate. Under no circumstances shall water be sprayed directly into the lay- down box while laying Microsurfacing material. I. Handwork: Areas which cannot be reached with the machine shall be surfaced using hand squeegees to provide uniform coverage. If necessary, the area to be hand worked shall be lightly dampened prior to mix placement. Care shall be exercised to leave no unsightly appearance from hand work. The same type of finish as applied by the spreader box shall be required. J. Edgelines: Care shall be taken to ensure straight lines along curbs and shoulders. No runoff on these areas will be permitted. Lines at intersections will be kept straight to provide a good appearance. If necessary, a suitable material will be used to mask off the end of streets to provide straight lines. Edge lines shall not vary by more than ± 2 inches (± 50 mm) horizontal variance in any 96 feet (30 m) of length. K. Clean-up: All areas, such as man-ways, gutters, and intersections, shall have the Microsurfacing mix removed as specified by the County. The contractor shall, on a daily basis, remove any debris associated with the performance of the work, completely and thoroughly to the satisfaction of the County. In addition, the contractor shall, at the request of the County pressure wash any area such as, curb and gutter, private driveways, etc. removing any and all stains associated with the placement of the Microsurfacing. L. General Performance: Provide completed pavement which performs to the satisfaction of the engineer without bleeding, rutting, shoving, raveling, stripping, or showing other types of pavement distress or unsatisfactory performance. M. Traffic Control: Traffic shall not travel on fresh mix until rolling and blotting has been completed. All traffic control shall be in accordance with the FDOT Roadway Design Standards and the current MUTCD. All associated devices shall be checked daily or more frequently as needed throughout the project for compliance. Where adjustments or corrections are needed, prompt revisions shall be made. VIII.

Carefully remove paper disks. 64 Pavement Management Alternative Methods Bid No. 15-601 Place specimens in 60°C forced draft oven with ventilation on sides and top. Place each specimen in a small container to account for material loss from the specimens. Care should be taken not to over-dry the specimens. Cure compacted specimens to constant weight but no more than 48 hours and no less than 16 hours. Constant weight is defined here as 0.05% change in weight in 2 hours. After curing, cool specimens at ambient temperature a minimum of 12 hours and a maximum of 24 hours. 5. Measurements - Determine bulk specific gravity (density) of each compacted (cured and cooled) specimen according to ASTM D2726. Determine specimen heights according to ASTM D3549 or equivalent. Alternatively, the height can be obtained from the SGC readout. Determine Rice (maximum theoretical) specific gravity, ASTM D2041, except as noted in Item 4 of this procedure, and do not break any agglomerates which will not easily reduce with a flexible spatula. Perform the supplemental dry-back procedure to adjust for uncoated particles. Determine percent air voids in accordance with ASTM D3203 for each design emulsion content. Determine corrected Marshall Stability by ASTM D1559 at 40°C after 2 hour temperature conditioning in a forced draft oven. 6. Moisture Susceptibility - Perform same conditioning and volumetric measurements on moisture-conditioned specimens as on other specimens. Vacuum saturate to 55 to 75 percent, soak in a 25°C water bath for 23 hours, followed by a one hour soak at 40°C. Determine corrected Marshall Stability.
