Research on Asphalt Overlay Technology of Urban Existing Cement Concrete Pavement

W U Heping

Abstract

It's common now of spreading asphalt overlay on the existing cement concrete pavement which has been used for a certain period.But the reflective crack will appear very quickly during the asphalt overlay,being the main damage of the structure plan.Combined with the crack principle and through the experiment section of West Tanzhong Road in Liuzhou,how to prevent and delay the appearance of the reflective crack is presented in the paper from 2 aspects including asphalt overlay structure design and existing pavement strengthening technique.
