Research on the Application of Ground Penetrating Radar Rapid Detection Technology for Asphalt Pavement——Taking the Detection of an Asphalt Pavement in Guangdong Province as an Example

近年来,我国交通运输业发展迅速,沥青道路的质量问题成为人们关注的焦点。其中,沥青路面的快速检测技术发挥了重要作用,探地雷达因具有高采样率、快速连续等特点,成为现阶段常用的快速检测工具之一。为分析探地雷达在沥青路面快速检测中的应用效果,文章介绍了探地雷达的组成和原理,并选取实际工程中的沥青路面进行检测测试,将探地雷达快速检测结果与实际路面厚度结果进行对比分析,试验结果表明,两种结果相近,离散小,为探地雷达在实际工程中的应用提供了参考。

In recent years, China’s transportation industry has developed rapidly, and the quality of asphalt roads has become the focus of people’s attention. Among them, the rapid detection technology of asphalt pavement plays an important role. Ground penetrating radar has become one of the commonly used rapid detection tools at this stage due to its high sampling rate, fast and continuous characteristics. In order to analyze the application effect of ground penetrating radar in the rapid detection of asphalt pavement, this paper introduces the composition and principle of ground penetrating radar and selects the asphalt pavement in the actual project for testing. The rapid detection results of ground penetrating radar are compared with the actual pavement thickness results. The test results show that the two results are similar and the dispersion is small, which provides a reference for the application of ground penetrating radar in practical engineering.
