摘要
为了研究地质雷达在路面检测中的可行性,基于乌奎高速公路改扩建项目,应用地质雷达对旧路路面结构厚度及结构内部病害进行检测。检测结果表明:地质雷达对路面厚度的检测误差在规范允许范围内,且地质雷达检测成像对典型路面结构病害有较为明显的特征表示;地质雷达可有效应用于路面评价,且可避免传统检测方法对路面结构的损坏。
In this paper,in order to study the feasibility of the geological radar in the pavement inspection,the geological radar is used to detect the thickness of the old pavement structure and the internal disease of the structure based on the reconstruction project of the Urumuqi-Kuitun Expressway.The results show that the detection error of the pavement thickness by geological radar is within tolerance and the geological radar image has obvious characteristics illustration to typical pavement structural diseases; The geological radar can be effectively applied to pavement evaluation,and unlike the traditional detection method,the damage of pavement structure can be avoided.
