ABSTRACT:
A method for making asphalt fibers includes supplying molten asphalt to a rotating asphalt spinner at a temperature between about 270.degree. F. and about 500.degree. F., centrifuging asphalt fibers from the asphalt spinner, and collecting the asphalt fibers. A method for integrating asphalt with reinforcement fibers includes establishing a moving veil of reinforcement fibers, such as glass fibers, and centrifuging asphalt fibers from a rotating asphalt spinner positioned within the veil of reinforcement fibers such that the asphalt is integrated with the reinforcement fibers. A method for making asphalt roofing shingles includes assembling together a mat of asphalt fibers with a mat of reinforcement fibers, coating the assembled mats to form an asphalt coated sheet, applying granules to the asphalt coated sheet, and cutting the asphalt coated sheet into roofing shingles. A method for producing highway reinforcement products includes collecting integrated asphalt and glass fibers on a reinforcement mat such as a glass grid.
