Zusammenfassung:	A method for producing asphalt fibers includes supplying molten asphalt to a rotating asphalt spinner, centrifuging asphalt fibers from the asphalt spinner, and collecting the asphalt fibers. The molten asphalt is supplied to the asphalt spinner at a temperature within the range of from about 270 DEG to about 500 DEG F. Also disclosed is a method for integrating asphalt with reinforcement fibers including the steps of establishing a downwardly 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 to integrate the asphalt with the reinforcement fibers. A method for making an asphalt roofing shingle includes the steps of 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. The invention also includes th
