Research on Detection to Moisture Content of Flexible Pavement by GPR

Moisture content is an important parameter due to its important influence on the serviceability of the pavement. Drainage is considered as one of most important factors in pavement projects. When water is trapped inside a flexible surface structure layer, it deteriorates surface layer and causes stripping, raveling and potholes in Hot Mixing Asphalt (HMA). Traditional methods to evaluate the pavement, for example, core-drilling can not meet the requirement to estimate the pavement moisture content effectively, because there are many disadvantages in this method such as low efficiency, bad representation, especially destruction to the pavement. Based on the above analysis, a new rapid, high efficient and nondestructive technology was proposed in this study. Ground Penetrating Radar (GPR) was developed recently, which is used widely for the pavement thickness detection. In this study, GPR was conducted to detect the moisture content of flexible surface, and the results demonstrate the effectiveness of the new kind.
