Study On The Technology Of Rubber Asphalt Production Technology Application

With the development of automobile industry, more and more waste tires, which not only pollute the environment occupation of land resources, but also easy to breed mosquitoes, spread diseases. Rubber asphalt road is a building material with excellent performance. Asphalt rubber hand can make full use of waste tires to reduce environmental pollution, and enhance the performance of low temperature anti-cracking and high temperature rutting resistance on the other hand. Based on Wei Fang rubber asphalt production line and Wei Gao Road maintenance cover engineering, the production process of rubber asphalt and its application is researched.The sampling analog line method is used to study the influencing factors of rubber asphalt production, the influence of rubber powder, rubber powder content, mixing process on the properties of rubber asphalt is determined. The influence of curing temperature on storage stability of asphalt rubber is also ensured, which provide technical support for the rubber asphalt production. Through the rutting, low temperature bending, immersion Marshall and freeze-thaw splitting test of rubber asphalt mixture pavement performance was analyzed systemically, at the same time to conduct a comprehensive evaluation of the mechanical properties of compression test and dynamic modulus test of rubber asphalt mixture of single shaft, which provide the theory support the use of rubber asphalt promotion. Combined with the rubber asphalt in the overlay maintenance engineering application, puts forward the construction control points of key process of rubber asphalt mixture mixing, paving and compaction, construction of rubber asphalt mixture.
