Research on Early Water Damage Detection and Prevention Measure of Highway Engineering Asphalt Pavement in Xizang
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.
