(OP)
What is the difference between type A and Type B asphalt

RE: Asphalt Types

I think the main difference between Type A and Type B Asphalt Concrete other than price/ton is that the Type A has a narrower band on grading (sieve analysis).
Meaning, Type B AC is more forgiving on the grading spec operating range.
Also, require high percent crushed particles on Type A and  lower sand equivalent requirement on Type B.
