    Abstract: A method for producing asphalt fibers (26) includes supplying molten asphalt (20) to a rotating asphalt spinner (10), centrifuging asphalt fibers (22) from the asphalt spinner (10), and collecting the asphalt fibers (26). The molten asphalt (20) is supplied to the asphalt spinner (10) at a temperature within the range of from about 270 DEG F (132 DEG C) to about 500 DEG F (260 DEG C). Also disclosed is a method for integrating asphalt (20) with reinforcement fibers including the steps of establishing a downwardly moving veil of reinforcement fibers, such as glass fibers (52), and centrifuging asphalt fibers (22) from a rotating asphalt spinner (10) positioned within the veil of reinforcement fibers to integrate the asphalt (20) with the reinforcement fibers. A method for making an asphalt roofing shingle (84) includes the steps of assembling together a mat of asphalt fibers (34) with a mat of reinforcement fibers, coating the assembled mats (70) to form an asphalt-coated sheet, applying granules (80) to the asphalt-coated sheet, and cutting (86) the asphalt-coated sheet into roofing shingles (84). The invention also includes the asphalt roofing shingle (84) made by this process. Further, the invention includes asphalt highway reinforcement products (116) containing asphalt fibers (26), and the method of making such products.

    Abstract: The present invention relates to an acoustical insulation material containing a first layer formed from a nonwoven web having a density of at least 50 kg/m 3 wherein the nonwoven web is formed from thermoplastic [meltblown] fibers having an average fiber diameter of less than about 7 microns; and a second layer of a high loft material. The high loft material of the present invention provides bulk to the first layer and may or may not have sound attenuating properties. Examples of the high loft material include, for example, fiberglass and high loft nonwoven webs. Also disclosed in a method of attenuating sound waves passing from a sound source area to a second area. The method includes positioning an acoustical insulation material containing a first layer formed from a nonwoven web having a density of at least 50 kg/m 3 wherein the nonwoven web is formed from thermoplastic [meltblown] fibers having an average fiber diameter of less than about 7 microns; and a second layer of a high loft material, between the sound source area and the second area.
