Wet Process for Recycling Asphalt Shingle in Asphalt Binder

摘要

A new method is disclosed for recycling waste asphalt shingles in hot mix asphalt, i.e. asphalt pavement construction. Ground asphalt shingles are treated as a binder component instead of as an aggregate component. The recycled asphalt shingles that are blended with virgin binder in a wet process act both as a partial binder replacement and as a binder extender due to the presence of fillers, rubber, and fibers in the processed material.
