Asphalt is very commonly used in our lives, such as asphalt laid modified asphalt on the ground, asphalt coatings, and asphalt products. Asphalt is composed of hydrocarbons of different molecular weights and their non-metallic derivatives. Asphalt has a very high viscosity organic liquid, generally liquid and black in color. The characteristics of asphalt are also very many, such as waterproof, good fire resistance, good moisture resistance, and good corrosion resistance. There are also many types of pitch, such as coal tar pitch, petroleum pitch and natural pitch. Then, let's talk about the knowledge modified asphalt about asphalt
What is Asphalt
Asphalt is a black-brown messy mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid and has a black surface. It is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic cementitious material. Pitch can be mainly divided into coal tar pitch, petroleum pitch and natural pitch: among them, coal tar pitch is a by-product of coking. Petroleum bitumen is the residue after the distillation of crude oil. Natural bitumen is stored underground, and some form mineral layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as pavement. If you have any other questions, please contact us modified asphalt for details or contact us directly.
