  • Wet Process for Recycling Asphalt Shingle in Asphalt Binder
    Publication number: 20140331897
    Abstract: 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.

  • Wet Process for Recycling Asphalt Shingle in Asphalt Binder for Asphalt Paving Applications
    Publication number: 20140299018
    Abstract: A method is disclosed for recycling asphalt roofing shingles and incorporating them into hot mix asphalt for use in applications such as asphalt pavement construction. Unlike previous methods, the asphalt from ground shingles is mixed with and becomes an integral component of the asphalt binder, instead of acting primarily as part of the aggregate. The asphalt content of the shingles mixes with heated asphalt binder to produce a single asphalt phase, and the asphalt from the shingles acts as asphalt in the final composite.
