CHARACTERIZATION AND MICROMECHANICAL

1.2 Recycled Asphalt Shingles Incorporation of roofing asphalt shingles into hot mix asphalt has been proposed for over 30 years. Asphalt roofing shingles make up nearly two-thirds of the roofing market for both new homes and roof replacements. In 1998 it was estimated that over 11 million tons of shingle waste is generated annually.
