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.
