Abstract

In order to study the road performance of rubber-cement stabilized gravel base, the road performance of rubber-cement stabilized gravel base is explored through different amount of rubber powder, mechanical properties of different cement dosage and crack resistance performance index. The apparent morphology of the specimen was tested by scanning electron microscope, and the structural characteristics and adhesion characteristics of different cement mixture and different rubber powder, the distribution characteristics of rubber powder in the mixture and the influence mechanism of the interface microsurface were analyzed. Through the comprehensive evaluation of mechanical properties, crack resistance and scanning electron microscope results, the results show that the cement hydration products and rubber powder form a mesh structure, which effectively disperse the stress through the network structure during the traffic load. Since the elasticity of rubber powder itself and good high temperature stability, the incorporation of rubber powder can effectively absorb the stress and strain generated by moisture evaporation during dry and temperature shrinkage, and maintain its own properties stable under temperature change, so as to reduce the temperature shrinkage and dry shrinkage coefficient of the mixture and reduce the generation of reflection cracks. In this study, the range of road grade applicable for different mix ratios is given through the unlimited compressive strength, which provides theoretical reference for selecting appropriate mix ratios according to road grade in actual engineering.
