摘　　要：为实现对沥青路面早期水损害的快速检测与评价,文章依托西藏地区某公路工程,借助地下探地雷达(GPR)技术,研究了沥青路面早期水损害检测方法与防治措施。文章首先分析了沥青路面水损害发生的原因,然后采用GPR技术识别出沥青路面含水区域,通过构造深度、摩擦系数、耐磨性等试验对检测结果加以验证,并提出了相应的防治措施。研究结果表明,采用GPR技术能精准识别出沥青路面水损害的位置,通过耐磨性指标能直接判断沥青路面水损害类型及程度。In order to realize the rapid detection and evaluation of early water damage in asphalt pavement,based on a highway project in Xizang,this paper studies the detection method and prevention measures of early water damage in asphalt pavement with the help of Ground Penetrating Radar(GPR)technology.It first analyzes the causes of water damage in asphalt pavement,and then uses GPR technology to identify the water-bearing area in asphalt pavement.The detection results are verified by tests such as structural depth,friction coefficient and wear resistance,and the corresponding prevention measures are put forward.The results show that GPR technology can accurately identify the location of water damage in asphalt pavement,and the type and degree of water damage in asphalt pavement can be directly judged by wear resistance index.
