In the course of 70 road construction asphalt, road asphalt material No. 70 selection must be based on topography, climate, population and other comprehensive factors road area, choose the appropriate bituminous material. When the selected material must ensure clean, clean, dry and warrants that the material has greater strength and wear resistance. 70 road asphalt pavement has four important characteristics: high temperature stability, low temperature crack resistance Sales No. 70 asphalt, water stability, fatigue resistance characteristics are widely used used in urban roads, pavement, airport runway , race track, national high-speed railway. Road Easen New Materials Co., relying on the advantages of Qilu Petrochemical resources, technology, personnel, etc., continue to develop new products and technologies, and improve product quality, technology and services to carry out tracking No. 70 asphalt prices to meet various types of asphalt products highway road requirements. Upgrade and maintenance emulsified asphalt mainly used for roads, there are many unique, other applications can not be replaced asphalt material at room temperature, low viscosity emulsion asphalt, good liquidity a road building material. It can be used at room temperature and can be cold and damp stone used together. In many applications, 70 road construction quality asphalt, emulsified asphalt provides a more secure than hot asphalt, energy-saving and environmentally friendly system, since this process avoids the high temperature operation, the heating and harmful emissions. Emulsified asphalt can be used for new road construction, such as a sticky layer of oil, through the layer of oil. A minute before the asphalt and AH, which is the general traffic bitumen and heavy traffic bitumen, No. 70 asphalt bitumen That hardness at room temperature of more than 90 to be hard, ability to resist high temperature deformation. Different road asphalt is used And to determine what pitch Jilin No. 70 asphalt according to the traffic volume and traffic loads and other related conditions, No. 70 asphalt manufacturers, road should be born of new materials (certified merchants) are provided by Shandong Zerui New Material Technology Co., Ltd ..
