Abstract:In order to improve road cement concrete deformation and small toughness traditional defects, rubber grain was mixed into concrete to form the rubber particles concrete; flexural modulus of rubber particles of concrete and ordinary concrete was comparative studied, two kinds of concrete damping change was analyzed by using the finite element, through three point concrete trabecular bending test, the fatigue properties were comparative researched, the rutting test methods were used in proving the rubber particles of concrete of erosion performance. According to the mechanical parameters of acquired in experiments, adopted the MEPDG 2002 design method, the road surface damage states were fore-casted of the two kinds of concrete pavement in the end period of design. Study results show that rubber particles cement concrete flexural modulus reduced by 12% than that of ordinary cement concrete, the damping ratio increased by 30%, the fatigue life have greatly improved, and surface erosion phenomenon did not happen, the rubber cement concrete slabs breakage was lower 30% than ordinary concrete. Therefore, the rubber particles concrete slabs can overcome the traditional defects of cement concrete pavement and with has excellent road performance.
