    • 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.degree. to about 500.degree. 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 the asphalt roofing shingle made by this process. Further, the invention includes asphalt highway reinforcement products containing asphalt fibers, and the method of making such products.
    • 制造沥青纤维的方法包括将熔融沥青供给旋转式沥青旋转器,从沥青旋转器离心沥青纤维,收集沥青纤维。 熔融沥青在约270°至约500°F的温度范围内供应到沥青旋转器。还公开了一种将沥青与增强纤维整合的方法,包括以下步骤:建立向下移动的增强纤维面纱, 例如玻璃纤维,以及将位于增强纤维的面纱内的旋转沥青旋转器离心沥青纤维,以将沥青与增强纤维相结合。 制造沥青屋顶瓦的方法包括以下步骤:将沥青纤维垫与增强纤维垫组合在一起,涂覆组装的垫以形成沥青涂布的片材,将颗粒施加到沥青涂布的片材上,并切割涂覆有沥青的沥青 板材成屋顶板。 本发明还包括由该方法制成的沥青屋顶瓦。 此外,本发明包括含有沥青纤维的沥青路面增强材料及其制造方法。
