Asphalt is an organic gelling material that is waterproof, moisture-proof and anti-corrosive. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt. Among them, coal tar asphalt is a by-product of coking, petroleum asphalt is the residue after crude oil distillation, and natural asphalt is stored underground.
