Abstract
A method for treating asphalt roofing shingles to be used for recycling in an asphalt plant which mixes asphalt roofing shingles with between about 15% and 50% by weight of a carrier aggregate. The aggregate is fed into a shredder with the shingles or is otherwise mixed with the comminuted shingles to form a recyclable asphaltic material which may be easily stored and transported, and which may also be used in the preparation of asphalt paving composition.
