摘要： A paving asphalt composition for improving the durability and longevity of asphalt road surfaces is disclosed. The paving asphalt composition includes asphalt base stock, heavy residuum of re-refined motor oil, and a chemical modifier. The heavy residuum of re-refined motor oil preferably has an API gravity of at least about 12, a kinematic viscosity greater than about 400 centistokes at 140.degree. F., a flash point greater than about 400.degree. F. and a mass loss less than about 3%. The paving asphalt composition may also include a polymer. A method of forming the paving asphalt composition and a method of paving roads are also disclosed.
