Experimental research on thickness reduction of rubber modified concrete pavement surface

This paper presents the results of flexural strength and flexural modulus tests on prismatic samples of rubber modified concrete with different rubber particle sizes (5-10meshes, 80mesh) and quantities (10kg/m³, 40kg/m³) which show that due to the lower flexural modulus the reduction of load and temperature stress is more than flexural strength. The study has found that compared to the common concrete the thickness of rubber concrete pavement surface decreases under the same equivalent rebound modulus of base top surface, which is an economical way for recycled tire utilization and also a new thinking in the thickness optimization of concrete pavement surface.
