The Company's production of crude oil and bitumen is the residue after distillation. Asphalt color black and shiny, with high temperature resistance. According to different levels of refinement, at room temperature into a liquid, semi-solid or solid. Petroleum bitumen can be classified according to the following system: 1, according to the production method is divided into: straight asphalt, bitumen oil solvent deasphalting, oxidized asphalt, blending asphalt, emulsified asphalt, modified asphalt; 2, according to the appearance of the form is divided into: liquid asphalt, solid bitumen, dilution, emulsion, modified; 3, use is divided into: asphalt roads, construction of asphalt, bitumen waterproof to use or function name of a variety of special asphalt. 4, the main purposes: as a basis for the construction of various departments materials, raw materials and fuel, the scope of application such as transportation (roads, railways, aviation, etc.), construction, agriculture, engineering, industrial (mining, manufacturing) and civil . Tips: asphalt production and use of the process may need to be stored in a holding tank, if not handled properly sell 70 road asphalt, bitumen can be repeated at a higher temperature heat can keep for a long time but its performance will not suffer serious damage. However, if the contact of oxygen, light and overheating can cause hardening of the asphalt, the most significant sign of the softening point of bitumen increased penetration decreased 70 road asphalt, ductility variation, so the use of performance asphalt suffer. 70 # asphalt road has many uses, receives calls from customers, buying 70 # asphalt roads and some for highways, one, two paved roads, some with a waterproof membrane and so on. Regardless of what to do in terms of the various buyers are that quality, because quality directly affect whether the smooth passage of vehicles on the road, good quality products, new materials, high temperature stability, high road extension should be raw, lasting adhesion sex. Bad quality products, service life is short, easy to rattle the ground. So you choose 70 # asphalt road when we must make a good off road asphalt paving special No. 70, after laying a road in a lot of costs, waste a lot of heart, when the final decision must employ a qualified 70 # 70 dedicated road asphalt paving asphalt road | Henan Province, No. 70 asphalt road | Road to Health Zerui new material provided by New Material Technology Co., Ltd., Shandong.
