Application rate of prime coat
A prime coat is a sprayed application of a cutback asphalt or asphalt The project plans specify the rate at which the prime coat is applied, and rates will vary 1 Mar 2018 SPECIFICATIONS FOR APPLYING PRIME COAT, BLOTTER, AND TACK the application rate and must be capable of providing an accurate, Apply bituminous prime coats on previously prepared bases, and apply application rate within the minimum and plus 0.01 gallon per square yard of the For cutback asphalts, the application rate is 0.4 to 0.5 gal/yd2. If the surface is smooth and tight 0.4 gal. is usually sufficient. Application Rate. Tack coat application should result in a thin, uniform coating of tack coat material covering approximately 90 percent of the pavement surface ( Surface King Tack & Prime Coat Applications With Asphalt Emulsions Deleting prime would lessen the amount of liquid asphalt contractors must handle,
surface treatment work including binder rate and aggregate rate design, material selection Selection of a prime coat binder type and an application rate.
Higher than recommended application rates resulted in slightly lower interface shear strengths. 14. Diluted slow set emulsions are typically used for tack coat.

When bonded, all layers working together. • Critical that tack materials are applied uniformly at appropriate application rate. • Apply tack coat on all surfaces.
(IDOT) changed the way it measures & pays for bituminous prime coat. increasing the degree of surface prep, cleaning & application parameters than with No separate payment will be made for prime coat under this Section. Include heating equipment and in distributor, for determining rate of application, and for.
Prime Coat should be left undisturbed for 24 hours so that it seeps down within the CABC and does not form a pond on CABC. Recently engineers are eliminating the use of Prime Coat due to certain studies which indicate that Prime Coat does not play any significant part in stability of pavement structure.
Prime sealing coat shall be MC30 or MC70 complying with ASSHTO M82 or as directed by the Engineer and shall be applied to the prepared sub-base layer at a rate between 0.8 and 1.2kg/m2 and at a temperature between 60' C and 80' C. Tests shall be carried out on site to determine the rate of spread of the prime sealing coat material. Types of material used as Prime Coat: Cut Back Asphalt or Emulsified Asphalt (Diluted) Application Rates: Cut Back Asphalt: 0.65 to 1.75 Litres / Sqm; Emulsified Asphalt: 2.3 to 6.8 Litres / Sqm; Lower application limit pertains to CABC which is very tight and has high fines content while upper limit pertains to highly porous CABC. Prime Coat / Tack Coat Rate of Application / Spreading Test | asphalt |, emulsion, bitumen emulsion test For more detail visit our website - https://www.cons Surface King Tack & Prime Coat Applications With Asphalt Emulsions . Prime Coat. A prime coat performs several important functions. At typically specified application rates, application rate had little effect on interface shear strength. Higher than recommended application rates resulted in slightly lower interface shear strengths. Types of material used as Prime Coat: Cut Back Asphalt or Emulsified Asphalt (Diluted) Application Rates: Cut Back Asphalt: 0.65 to 1.75 Litres / Sqm. Emulsified Asphalt: 2.3 to 6.8 Litres / Sqm The project plans specify the rate at which the prime coat is applied, and rates will vary from one project to another. Generally, however, medium curing cutback asphalt is applied at a rate between 0.2 to 0.5 gal./SY, and emulsified asphalts are applied between 0.1 to 0.3 gal./SY.
