[Abstract]:Based on the theory of interface and solubility, the mechanism of asphalt modified by rubber powder is analyzed by advanced testing method, and the performance of rubber powder and asphalt modified by rubber powder is studied. According to the characteristics of rubber powder modified asphalt mixing system, the adaptability analysis of existing evaluation index and test method is carried out, and the indoor preparation technology is optimized to guide the field production. Based on the GTM rotational shear mechanics method, the composition design of rubber powder modified asphalt mixture was optimized, and the continuous gradation optimization scheme of embedded bias skeleton was put forward, and the road performance was taken as criterion. Based on the theory of interlayer combination, the interlayer stability of asphalt modified by rubber powder as waterproofing and bond layer of cement concrete bridge deck is studied systematically. A complete set of construction quality control scheme is summarized through solid engineering, and applied to solid engineering through indoor research results, according to the characteristics of rubber powder modified asphalt mixture and the level of existing construction machinery configuration, the field construction quality control scheme is put forward. It provides theoretical support and technical support for the application of waste tire rubber powder modified asphalt and its mixture.
