Research On Asphalt-Rubber Production And Road Performance

laboratory experiment is an important factor which Restrict the development of Rubber Asphalt, This thesis in-depth analysis the problems of the laboratory experiment production and Combine the Special requirements of Rubber Asphalt production, invent the rubber asphalt reactor which used to the laboratory experiment production.By using the index, the viscosity, ductility, penetration, softening point, elastic recovery of the rubber asphalt, make necessary research on the production of the rubber asphalt, then set up the indoor process preparation of production.By studying the conventional indicators of the rubber asphalt, coming to three conclusions, firstly, matrix asphalt is the major factor in the quality of rubber asphalt, It should be considered that the matrix asphalt should meet the climate district and the functional requirements, then design the mesh count and content. Secondly, the greater mesh count, the better of the performance of rubber asphalt. Third, with the different ingredient of the rubber asphalt, there is a balance of different content, the incorporation of rubber powder will play a negative role if the balance has been surpassed. With the efforts of the Water stability and Rubber asphalt synchronization crushed stone sealing course boundary strength, from the perspective of using purpose and the environment, the design of content and mesh count of the rubber powder has been studied confirmatory. There are two conclusions, first, the greater the mesh count, the worse the mixture of water temperature and the Rubber asphalt synchronization crushed stone sealing course boundary strength. Second, there be a balance in the content, the content of the rubber asphalt for spreading is larger than that in the balance of the mixture. To solve the problem of the poor water stability in the rubber asphalt mixture, using the cement instead of the mineral powder, it found that the water stability has been improved greatly in the water stability test, it can achieve improved objective.
