摘要
针对某高速公路的水损坏现象开展钻芯调查,对芯样的空隙率、厚度、油石比和级配进行了全面测试,并开展了现场渗水试验,从材料和结构角度分析了路面结构产生水损坏的原因。
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.
