Abstract: Improved cold-applied asphalt compositions for use as sealants, cements, coatings and the like, including recycled asphalt roofing wastes, and asphalt. Recycled roofing wastes provide an excellent, although unexpected, source of temperature-stable asphalt, stabilizing filler, and reinforcing fiber, which provides compositions having exceptional performance characteristics as well as the reduction or elimination of asbestos from such compositions. Use of asphalt roofing wastes allows for recycling of a non-renewable resource and provides an environmentally-safe alternative to landfill disposal of such materials.
Abstract: An improved cold patch composition for pavement repair and method of preparation therefore, including recycled asphalt roofing waste, aggregate, and solvent. Recycled asphalt roofing waste provides an excellent, although unexpected, source of asphalt, filler, and fiber, which when used in conjunction with the method of this invention provides compositions having remarkable engineering performance properties quickly upon application, with little cure time. Use of asphalt roofing wastes represents a means of recycling a non-renewable resource and providing an environmentally-safe alternative to landfill disposal of such materials.
Abstract: An improved asphalt pavement composition including about 3-8 parts by weight asphaltic bitumen binder; about 62-96 parts by weight aggregate; and about 0.5-30 parts by weight recycled roofing waste as a predominate source of asphalt, stabilizing filler and reinforcing fiber. Use of recycled asphalt roofing waste at any level provides an excellent pavement composition which exhibits enhanced performance properties. A non-renewable resource is thus recycled, while providing an environmentally-safe alternative to landfill disposal.
