Mechanically powdered substance obtained after crushing waste tires is 30 mesh crumb rubber powder, its production process is grinding method at room temperature, cryogenic grinding method, water hammer method. Compared with reclaimed rubber, rubber powder without desulfurization, so less energy-consuming production process rubber powder, reclaimed rubber process is relatively simple and more, reduce pollution, and crumb rubber powder high performance waterproofing membrane, extremely versatile. To recycle waste tire rubber powder production is set by the environmental protection and resource recycling in one of the promising ways. Waste tire rubber powder and SBS modified bitumen compound can take full advantage of SBS modified asphalt rubber powder and powder two kinds of modifiers, and reduce the amount of SBS, reduce costs 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.
