Abstract

The damage of road base course has the characteristics of strong concealment and difficulty in detecting. For this reason, the impact imaging method has been used for detection of road base course. This paper discussed systematically collection points setting, excitation mode and data processing method. Through the application in testing for highway pavement base before and after grouting maintenance, the results show that the method is simple and accurate. The detection results can be displayed in a two-dimensional image form and it is easy to be used in road maintenance. This method can be used to identify and locate the damages of the pavement base, to judge the uniformity of the pavement base structure. It can also be used to evaluate the effectiveness of internal damage after grouting repairing.

摘要

道路基层病害具有很强的隐蔽性且检测困难。为此，采用冲击成像法对道路基层进行检测。本文系统地探讨了采集点设置、激发方式及数据处理方法。通过在公路路面基层注浆养护前后检测中的应用，结果表明该方法简单、准确。检测结果能够以二维图像的形式显示，便于在道路养护中应用。该方法可用于识别和定位路面基层病害，判断路面基层结构的均匀性，还可用于评估注浆修复后内部病害的修复效果。
