What is the minimum and maximum curing time of asphalt prime coat?

There are no curing time requirement for prime coat.

You can asphalt rigth away after your prime as long as the prime have the proper temperature.

There are curing time for TACK COAT which is different. (TACK IS OVER ASPHALT,PRIME IS OVER BASE ROCK ).Is a common mistake confuse those two different operations.

The curing time for TACK depend of the weather and varie between 8 hrs to 24 hrs.
