Asphalt is the residue of crude oil
Difference: Asphalt is composed of different molecular weight hydrocarbons and non-metallic derivatives of dark brown complex mixture, is a high viscosity organic liquid, was liquid, the surface was black, soluble in carbon disulfide. Asphalt is a waterproof moisture and corrosion of organic cementitious materials. Asphalt can be divided into coal tar pitch, petroleum asphalt and natural asphalt three: Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural asphalt is stored in the ground, and some of the formation of ore or in the crustal surface accumulation. Asphalt is mainly used for coatings, plastics, rubber and other industries and pavement and so on. Crude oil (44.27,0.27,0.61%) is the upstream raw material of asphalt, there is a strong correlation between the two prices. For the asphalt industry, the impact of the upstream industry is mainly reflected in the fluctuations in crude oil prices, crude oil processing capacity changes in oil asphalt production and product prices fluctuations. From the downstream demand point of view, asphalt products are mainly used in highways, municipal roads, bridges and airports and other places of the laying of which highway construction for the consumption of asphalt accounted for 82%. In the case of a certain capacity, the increase in downstream demand will further promote the growth of asphalt prices, on the contrary, will bring the price down.
