[Abstract]:The application of waste tires in road construction technology can improve the quality of highway engineering, prolong the service life of road surface, and accord with the basic strategy of saving resources and protecting environment advocated by the state. Rubber asphalt and mixture have unique advantages in thinning pavement, prolonging pavement service life, delaying reflection crack and reducing traffic noise. This paper focuses on the factors affecting the performance of rubber asphalt and its manufacturing process, the design and performance of rubber asphalt mixture and the engineering application of rubber asphalt concrete. Firstly, the rubber powder and rubber asphalt are introduced. Combined with the action mechanism of rubber asphalt, the indoor test method of rubber asphalt performance evaluation in the research process is briefly introduced, and the influence of various factors on rubber asphalt performance is analyzed. It includes material factors (particle size of rubber powder, type of rubber powder, amount of rubber powder and type of matrix asphalt) and technological factors (shear temperature, shear rate and shearing time). Including dry construction technology and wet construction technology. Secondly, the technical index of raw material of rubber asphalt mixture is put forward. This paper introduces the gradation design of rubber asphalt mixture (volume filling method), the selection of gradation, the optimum asphalt content and the verification of mixture performance. Two kinds of rubber asphalt mixture, broken grade rubber asphalt mixture and open grade rubber asphalt mixture, are put forward. Finally, through the engineering application of rubber asphalt in Guangdong area, the raw materials, mix ratio design, construction technology and quality control of rubber asphalt mixture are introduced.
