GILSONITE MODIFIED ASPHALT EMULSION SEAL COATS

1.1 MEASUREMENT AND PAYMENT PROCEDURES

Measure the quantities of gilsonite modified asphalt emulsion used in the accepted work and to be paid for, provided that the measured quantities are not more than 10 percent over the test section determined application rate. Any amount of gilsonite modified asphalt emulsion more than 10 percent over the test section determined application rate for each application will be deducted from the measured quantities except for irregular areas where hand spraying of the bituminous material is necessary.

1.1.1 Gilsonite Seal Coat Measurement Methods

The area of applied emulsion and to be paid for will be measured in square yards.

1.1.2 Payment

The approximate amounts of materials per square meter square yard for gilsonite modified asphalt emulsion used in production must be as provided in Table 6 for the treatment area[s] at the specified dilution rate[s] as noted. The actual application rates will vary within the range specified to suit field conditions and will be recommended by the manufacturer's representative and approved by the Contracting Officer from test areas and sections evaluated.

1.3 SYSTEM DESCRIPTION

1.3.1 Equipment, Plant and Tools

Equipment, plant and tools used in the work are subject to Government approval and must be maintained in a satisfactory working condition at all times. Provide equipment which is adequate and has the capability of producing the results specified. Provide calibrated equipment, such as asphalt distributors, spreaders and similar equipment, that has been recalibrated by an approved calibration laboratory within 12 months prior to commencing work and every 6 months thereafter, by such laboratory from the date of recalibration, during the term of the contract. Submit an equipment list with calibration reports.

1.3.2 Asphalt Distributors

The emulsion must be applied with an equipment manufacturer-approved computer rate-controlled bituminous distributor. The equipment must be in good working order and contain no contaminants or diluents in the tank when product to be applied is added to the tank. Spreader bar tips must be clean, free of burrs, and of a size to maintain an even distribution of the emulsion. Any type of tip or pressure source is suitable that will maintain predetermined flow rates and constant pressure during the application process with application speeds under 13 kilometers per hour eight miles per hour or 213 meters per minute 700 feet per minute. Test the equipment under pressure for leaks and to ensure it is in good working order before use.

The distributor truck must be equipped with a spreader bar with individual nozzle control. The distributor truck must be capable of specific application rates in the range of 0.15 to 0.80 liters per square meter 0.05 to 0.25 gallons per square yard. These rates must be computer-controlled rather than mechanical. The distributor truck must have an easily accessible thermometer that constantly monitors the temperature of the emulsion.

In the event of a temperature problem with the material, a distributor truck will be provided that is equipped to effectively heat and mix the material to the required temperature prior to application.

Heating and mixing will be done in accordance with the manufacturer's recommendations. Care must be taken not to overheat or over mix the material.

The distributor must be equipped to hand spray the emulsion in areas identified either on the plans or by the Contracting Officer.

1.3.3 Power Brooms and Power Blowers

A power broom or blower must be provided for removing loose material from the surface to be treated.

1.3.4 Vacuum Sweepers

Provide self-propelled, vacuum pickup sweepers capable of removing loose sand, water, and debris from pavement surface.

1.3.5 Equipment Calibration

Equipment calibration for emulsion may be achieved by either one of the following procedures:

a. Second Procedure: Furnish all equipment, materials and labor necessary to calibrate the asphalt emulsion distributor. Perform all calibrations with the approved job materials and prior to applying the specified coatings to the prepared surface. Perform calibration of the asphalt emulsion distributor in accordance with ASTM D2995. Perform work to calibrate the tank and measuring devices of the distributor. Perform inspection and calibration at the beginning of the work and at least once a day during construction.
