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.
