Waste tire rubber powder and SBS modified bitumen compound can take full advantage of SBS modifier with two kinds of powder and reduce the amount of SBS 80 mesh rubber powder, reduce the cost of modified asphalt. The problem is: the composite powder and SBS modified asphalt existing preparation process is not mature enough; about how to determine the composite powder and SBS modified asphalt modifier reasonable two kinds of research content is still not perfect, did not offer reasonable dosage; for composite powder and SBS modified asphalt pavement performance evaluation system is not enough. The manufacture of rubber powder modified asphalt modified asphalt, and asphalt, asphalt oil, and raw material blending flocculants good combination. Modified bitumen produced by resurfacing wear, spalling resistance greatly improved rubber powder, wear life of 2 - 3 times the normal road surface, reducing road maintenance costs 30 - 50%. According to the test: 8000 vehicles per day flow through the use of 5-year and 30 mesh rubber powder, no white, soft, pushing pro package and cracking phenomenon, and can make braking distance of the vehicle by 25%, can significantly improve traffic safety. The product is manufactured using bitumen caulking ointment effectively improve the softening point of the product, increasing the low elongation.
