There are two main variations of the Prime Coat process:
Sprayed Prime Coat - Cutbacks, Prime Asphalt Emulsions, Non-Asphalt Emulsions
Mixed Prime Coat - Mixing Grade Emulsions
Waiting Period Before Paving
Following application of the prime material and prior to application of the succeeding layer of asphalt mixture, allow the prime coat to cure and water or volatiles to evaporate. This may take 24 hours for emulsion primes and 72 hours for cutback primes depending on site and weather conditions.
