Abstract: 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.

Abstract: An improved apparatus and method for cooling asphalt, which includes a cooling zone, such as a cooling chamber through which coolants such as air and water are blown or drawn, and an elongated conveyor for transporting asphalt molds through said cooling zone after said asphalt molds have been lined with plastic and filled with hot asphalt.

Abstract: A packaging for roofing asphalt comprising a polypropylene film 1.0 to 1.8 mils thick with a melting point between 275.degree. F. and 335.degree. F. as the sole containment, and a method for manufacturing the same are disclosed.

Abstract: An apparatus and method for packaging asphalt, which includes liquid cooling means, such as a pool or water sprayer, and an elongated flat conveying surface, such as the surface of a conveyor belt, for transporting asphalt molds into said liquid cooling means after said asphalt molds have been lined with plastic and filled with hot asphalt.
