Asphalt is a waterproof, dampproof and anticorrosive organic cementing material. Asphalt can be mainly divided into coal tar asphalt, petroleum asphalt and natural asphalt: among them, coal tar pitch is a byproduct of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, and some are formed into mineral deposits or accumulated on the surface of the crust. Asphalt is mainly used in industries such as paint, plastics, rubber and the like, and paved roads and the like.
