ABSTRACT:
A method for reclaiming waste asphalt sheet material reinforced with inelastic brittle fibers, such as fiberglass, subjects the material to tearing, kneading, sheet and frictional drag forces, preferably in a kneading mixer, to reduce the material to a viscous fluid state in which the fibers have been pulverized to particles of a maximum dimension less than about 600 microns. If mineral particles of larger dimension are present in the reduced fluid material, they are crushed to filler particles of maximum dimension less than about 600 microns by passing the reduced fluid material between oppositely rotated, heated crush rolls. The novel reclaimed waste includes at least the asphalt and the pulverized fiber, may include mineral filler of maximum particle size less than 600 microns, some or all of which may be crushed mineral granules of larger maximum dimension contained in the waste material.
