General This section covers the seal coating of existing (aged) parking lots using refined coal tar slurry seal coat with additive over the existing (aged) asphaltic concrete pavement to improve the lot prior to re-striping B. Description The successful bidder must provide primer and one coat of refined coal tar emulsion sealer with additive in all areas. Materials A. Refined Coal Tar Emulsion A refined coal tar emulsion prepared from a high temperature refined coal tar conforming to the requirements of ASTM specification 0490 for RT12. The use of oil and water gas tar is not

2 allowed. Base refined coal tar emulsion must conform to all requirements of Federal Specification RP-355. B. Aggregate Use washed dry silica sand or boiler slag free of dust, trash, clay, organic materials or other contaminants. This aggregate should meet the following gradation requirements: Percent Retained Sieve Size Minimum Maximum TABLE 1 #20 or coarser (0.850mm) 0-2 #30 (0.600mm) 0-12 #40 (.425mm) 2-60 #50 (0.300mm) 5-60 #70 (.212mm) 5-60 #100 (0.150mm) 5-30 #140 (.l06mm) 0-10 #200 (.075mm) 0-2 Finer than # This table represents the maximum range of aggregate gradations. In all cases the refined coal tar emulsion supplier is to give written approval of the aggregate used in the mix design. C. Additive As specified by the coal tar emulsion manufacturer. Water: Use water for mixing that is potable and free of harmful soluble salts. Control water temperature so it is at least 50 F (10 C). Crack Sealant: Oil Must be certified for compatibility with the refined coal tar emulsion by the manufacturer of the refined coal tar emulsion, and approved by the engineer. Spot Primer: Must be certified for compatibility with the refined coal tar emulsion by the manufacturer of the refined coal tar emulsion, and approved by the engineer. Pavement Primer: Must be certified for compatibility with the refined coal tar emulsion by the manufacturer of the refined coal tar emulsion, and approved by the engineer. Composition: The refined coal tar emulsion seal coat is to consist of a mixture of refined coal tar emulsion, water, additive and aggregate, and be proportioned as shown in the following table:

3 TABLE 2 Type of Seal Coat Composition & Quantities Water Aggregate Rubber Application Rates Gal./gal of emulsion Lbs./gal. of emulsion Gal./gal/ of emulsion Gal./space/yd. per application Rubberized Sand 0.80 (max) Slurry Rubberized 0.80 (max) Emulsion Sand Slurry 0.15 (max) Plain Emulsion 0.10 (max) D. Application Rate Application rates are not to exceed 0.17 gal/yd/coat, and at no time are total coats to exceed 0.51 gal/yd. E. Precautions Sealer should not be applied unless pavement temperature is at least 50 F (IO C) and the air temperature is 50 F (IO C) and rising. Sealer should not be applied during rainy or wet weather, or when rain is anticipated within eight hours after application is completed. Sealer should not be applied to hot surfaces under the summer sun (over 90 F, ambient) without first cooling the surface with clean water. Water should dampen the surfaces without leaving puddles. Since an emulsion may be damaged by freezing, it should be protected at all times when the temperature drops below 40 F (4 C). Execution A. Crack Sealing Remove all vegetation and debris from cracks to a minimum depth of 1/2. If extensive vegetation exists treat the specific area with a concentrated solution of a water-based herbicide approved by the engineer. Fill all cracks, ignoring hairline cracks (<1/2" wide) with a crack sealant. Wider cracks (over ½ wide (38.4mm)), along with soft or sunken spots, indicate the pavement or the pavement base should be repaired or replaced as indicated in the above specifications for Patching. B. Mixing I. Blend the coal tar emulsion mixture in equipment described in equipment section of these specifications using the ingredients described in Table 2. During the entire mixing and application process, no breaking, segregating, or hardening of the emulsion, nor balling or lumping of the sand is to

4 be permitted. Continue to agitate the seal coating mixture in the mixing tank at all times prior to and during application so that a consistent mix is available for application 2. Small additional increments of water may be needed to provide a workable consistency, but in no case is the water content to exceed the specified amount. C. Application of Aggregate Filled Seal Coat 1. Water Fog: To provide maximum adhesion the engineer may require water fog spray (dampening). 2. Prime Coat: As needed. 3. First Coat: Apply the mixture uniformly to obtain the rates specified in Table Drying and Initial Cure between Coats: Allow each coat to dry and initially cure before applying any subsequent coats. 5. Additional Coats: Additional coats may be applied over the entire surface or in heavy traffic areas such as drive lanes. 6. Final Look: The finished surface must present a uniform texture. D. Drying and Initial Cure I. The final coat must be allowed to dry a minimum of eight hours of good daylight drying conditions before opening to traffic, and initially cure enough to drive over without damage to the seal coat. 2. If marginal weather conditions exist during this eight hour drying time, additional time will be required. In some cases this could exceed 24 hours. 3. Check the surface after this for traffic ability before opening it to vehicle traffic. Equipment and Tools: A. Distributors Distributors or spray units for the spray application of the seal coat shall be self-propelled and capable of uniformly applying 0.15 to 0.55 gallons per square yard (0.69 to 2.5 liters per square meter) of material over the required with of application. Distributors shall be equipped with removable manhole covers, tachometers, pressure gauges, and volume measuring devices. The mix tank shall have a mechanically powered, full-sweep, mixer with sufficient power to move and homogeneously mix the entire contents of the tank. The distributor shall be equipped with a positive placement pump so that a constant pressure can be maintained on the mixture of the spray nozzles. B. Mixing Equipment The mixing machine shall have a continuous flow mixing unit capable of accurately delivering a predetermined proportion of aggregate, water, emulsion (and rubber) and of discharging the thoroughly mixed product on a continuous basis. The mixing unit shall be capable of thoroughly blending all ingredients together and discharging the material to the spreader box without segregation. C. Spreading Equipment Attached to the mixing machine, the spreading equipment shall be a mechanical type squeegee distributor, equipped with flexible material in contact with the surface to prevent loss of slurry from the spreader box. It shall be maintained to prevent loss of slurry on varying grades and adjusted to assure uniform spread. There shall be a lateral control device and a flexible strike-off capable of being adjusted

5 to lay the slurry at the specified rate of application. The spreader box shall have an adjustable width. The box shall be kept clean; coal-tar emulsion and aggregate build-up on the box shall not be permitted. D. Calibration The Contractor shall furnish all equipment, materials and labor necessary to calibrate the equipment. It shall be calibrated to assure that it will produce and apply a mix that conforms to the job mix design. Commercial equipment should be provided with a method of calibration by the manufacturer. All calibrations shall be made with the approved job materials prior to applying the seal coat to the pavement. A copy of the calibration test results shall be furnished to the Engineer. E.
