沥青路面构造深度检测方法及其应用

Depth detection method and application of asphalt pavement structure

为准确检测沥青路面的构造深度,将沥青路面构造进行分类,同时简要介绍了目前常用的几种沥青路面构造深度的检测方法,并以某高速公路为例,对该路面分别采用铺砂法和激光构造深度仪法进行检测。检测结果表明:不同检测方法的检测结果基本一致,前者检测结果为1.88 mm,后者为1.89 mm,均满足规范要求,该测试路段抗滑性能良好。在检测结果的基础上进行了皮尔森相关系数分析,其相关系数达到0.970 6,表明2种方法在沥青路面构造深度检测上均具有良好的准确性。

To accurately detect the depth of asphalt pavement structure,this article classifies the asphalt pavement structure and briefly introduces several commonly used methods for detecting the depth of asphalt pavement structure.Taking a certain expressway as an example,the pavement was tested using the sand laying method and laser construction depth meter method.The test results showed that the test results of different methods were basically consistent,with the former testing result of 1.88 mm and the latter testing result of 1.89mm,both meeting the standard requirements.The test results showed that the anti-skid performance of the test section was good.Based on the detection results,Pearson correlation coefficient analysis was conducted,and the correlation coefficient reached 0.97,indicating that the two method has good accuracy in detecting asphalt pavement construction depth.
