| Abstract: | Through drilling the core from one highway,the parameters of the pavement,such as void,thickness,asphalt-aggregate ratio and gradation of the asphalt concrete are measured.The permeability of the pavement is also measured in field.From the point of the structure and material of old asphalt pavement,the reasons of water damage in the pavement are analyzed. |
