| Abstract: | Asphalt in the Asphalt concrete pavement of expressway will lose the bonding stress because of the action of the water so that it will fall off from the mineral, which will bring relax, pit and emit slurry etc. At last it will affect the normal use of the pavement. This paper analysis the cause and mechanism of the asphalt concrete pavement on the base of the road disease investigation of the Zheng-zhu expressway, and bring forward the method and measure to protect the pavement from the water breakage. |
