PRIME COAT FOR BASE COURSES

DIVISION 2- SITE WORK DESCRIPTION

Furnish all labor, materials, equipment and incidentals required to prime and tack coats for base courses the work includes, but is not limited to, cleaning, applying prime and tack material, covering rolling and any other miscellaneous work and clean-up required.

PRODUCTS

2.01 MATERIALS

Prime Coat: FDOT Spec. Section 300, Prime and Tack Coats for Base Courses, excluding the statement: “The Engineer will designate the actual temperature to ensure uniform distribution.” from Paragraph 300-6.1, General; and "The Engineer will designate the curing period for the tack coat" from Paragraph 300-7.5, Curing and Time of Application. The Contractor will be responsible for those determinations.

EXECUTION

3.01 GENERAL

A. Cleaning the Base: Before any bituminous material is applied, remove to the shoulders all loose material, dust, caked clay, and foreign material which might prevent proper bond with existing surface. Take particular care to clean the other edges of the strip to be treated to insure that tack coat will adhere. Where the prime or tack coat is applied adjacent to curb and gutter or valley gutter, such concrete surfaces are to be protected and kept free of bituminous material.

B. Weather Limitations: Do not apply bituminous material when the air temperature is less than 40 degrees F. in the shade, when the weather conditions or the condition of the existing surface is unsuitable, while rain is falling or when there is water on the surface to be covered.

C. Equipment: Use a pressure distributor equipped with pneumatic tires having a sufficient width of rubber in contact with the road surface to avoid breaking the bond or forming a rut in the surface. The distance between the centers of the openings of the outside nozzles of the spray bar shall be equal to the width of the application required, within an allowable variation of two inches. The outside nozzle at each end of the spray bar shall have an area of opening not less than 25 percent, nor more than 75 percent in excess of the other nozzles.

All other nozzles shall have uniform openings. When the application covers less than the full width, the normal opening of the end nozzle at the junction line may remain the same as those of the interior nozzles.

02999-15

3.02 APPLICATION OF PRIME COAT

A. The surface to be primed will be clean and dry. For limerock bases, the glazed finish will have been removed as specified. Temperature of prime material will be between 100 and 150 degrees F. The exact temperature will be such as to insure uniform distribution. Apply bituminous material at the rate of approximately 0.10 to 0.25 gallons per square yard, dependent upon the type of base material, sufficient to coat the surface thoroughly and uniformly without having any excess to form pools or flow off the base. Application rates shall be in accordance with D.O.T. Specifications 300-6.

B. Apply a light, uniform application of clean sand or screenings prior to opening the primed base to traffic and roll with a traffic roller in conjunction with traffic to cure the prime coat. If warranted by traffic conditions, apply only on one-half of the width of the base at one time, care being taken to secure the correct amount of bituminous material at the joint.
