Genetic Analysis of the Disease of Asphalt Overlay on Existing Cement Concrete Pavement and Countermeasure

Based on the disease investigation and correlative laboratory experiment of asphalt overlays,the main disease types and genesis were analyzed about asphalt overlay on existing cement concrete pavement,and the corresponding controlling measures and countermeasures were put forward to perfect the design,construction and maintenance technology of asphalt overlay on existing cement concrete pavement.So it offords a reference to enhance pavement quality and delay pavement service life.
