Experimental Analysis of Failure Modes and Pavement Strength Control Parameters to Existing Cement Concrete Pavement

Abstract:

Cement concrete pavement as a common form of the road has been widely used because of its high strength, stiffness, and good durability characteristics. In order to explore failure modes and the strength control factors of the cement concrete pavement in the region, site investigation and the orthogonal test method in laboratory are used. Test combination design for the main control factors of the cement concrete strength was executed based on orthogonal test method. Strength of concrete specimen was determined by using indoor pressure test machine. The results show that the chiefly control parameter of affecting concrete strength is water cement ratio and the following are sand ratio and the coarse aggregate grading.
