It is a kind of high-viscosity organic liquid, in liquid form, with a black surface, and soluble in carbon disulfide. 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, some of which forms mineral layers or accumulates on the surface of the earth's crust. Asphalt is mainly used in industries such as coatings, plastics, and rubber, as well as in paving roads. During the use of existing mixing devices for preparing asphalt pavement materials, the asphalt mixture at the bottom of the device is often not fully stirred when the device is mixing the asphalt.
