Cement Concrete Pavement Cause Of Damage And Asphalt Overlay Technology Research

Based on the investigation and analysis on the design structure, factual structure, damage, drainage, traffic volume, construction of cement concrete pavement in Zhengzhou , this paper finds out the defect on design, construction and maintenance of cement concrete pavement, and discusses the main reasons which cause it to damage in theory and practice. Then it carries out relatively systematic research for the asphalt concrete overlay on old concrete pavement, and raises the design and construction methods of asphalt concrete overlay on old concrete pavement. The engineering shows that asphalt concrete overlay can improve maintenance quality of the present cement concrete pavement and prolong its service life.
