[Abstract]:At present, most of the green ecological road mixtures at home and abroad are warm mixed modified asphalt mixture and rubber powder modified asphalt mixture, while the research on warm mixed rubber powder modified asphalt mixture is less, which is at the time of vigorously promoting the construction of green ecological road. It is of great practical significance to develop asphalt mixture with good road performance and environmental protection effect. In this paper, the research status of warm mixed rubber powder modified asphalt mixture at home and abroad is investigated comprehensively, and the Rheological properties, road performance, environmental protection performance and construction quality control are systematically studied in combination with the existing technical experience. The action mechanism, manufacturing process and environmental protection effect of warm mixed rubber powder modified asphalt are revealed deeply, and the experimental road paving of warm mixed rubber powder modified asphalt mixture is carried out to test its application effect in practical engineering. The main contents of this paper are as follows: (1) the preparation process of warm mixed rubber powder modified asphalt was determined, the viscosity, low temperature performance and high temperature performance of warm mixed rubber powder modified asphalt were measured by orthogonal test, and the fineness of rubber powder was evaluated. The effects of three factors, such as the content of rubber powder and the content of warm mixing agent, on the Rheological properties of asphalt modified with warm mix rubber powder. (2) based on the "volume design method", the mixture proportion design of modified asphalt mixture with warm mixed rubber powder was carried out. The effects of the fineness and content of rubber powder on the road performance of rubber powder modified asphalt mixture were compared and analyzed under the condition of warm mixing. And the change law of road performance of rubber powder modified asphalt mixture under different warm mixing process conditions. (3) through indoor sound absorption coefficient test and field noise monitoring, the noise reduction effect of warm mix rubber powder modified asphalt mixture is deeply studied. Through the calculation of heat formula and the actual test, the environmental protection effect of warm mixed rubber powder modified asphalt mixture was evaluated. (4) the test road paving of warm mixed rubber powder modified asphalt mixture was carried out. The construction technology and construction quality control of warm mixed rubber powder modified asphalt concrete are systematically studied, and the performance and engineering application effect of warm mixed rubber powder modified asphalt mixture are verified at the same time. It provides the basis for the popularization and application of warm mixed rubber powder modified asphalt mixture.
