The modified asphalt emulsified asphalt specially developed by SBS (Ultra Thin Abrasion Layer) of China Drying Network was developed and produced by Chang Lian. After the recent use of some expressways in Hunan Province, it was tested by Hunan Highway Management Department. All indicators met the technical requirements and were well received by users. . Chang Lian also broke the foreign monopoly of the product's production technology. In recent years, high-quality bitumen has become the leading product in the construction of various medium and high-grade highways, and road maintenance and minor damage repairing projects are becoming increasingly large. Among them, SBS special modified emulsified asphalt is mainly used for pavement preventive maintenance and minor damage repair, which can effectively enhance road safety and extend the service life of the road. To this end, the long-smelting SBS modified emulsified asphalt technical group, while stepping up research on the subject, conducted academic exchanges with the Academy of Petroleum Sciences and universities in Hunan and Hubei, etc., and comprehensively performed the process route, production formula and process control of the product. explore. "After a large number of tests, we have solved a series of technical problems and paved the way for the industrialized production of special modified emulsified asphalt for ultra-thin wear layers." Tang Guoxiang, the production department of the asphalt plant, said. The use of terminal market for more than one month showed that the performance of long-term modified SBS modified emulsified asphalt was stable, and some of the indicators were better than foreign products.
