Depth detection method and application of asphalt pavement structure
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 express-way as an example,the pavement was tested using the sand laying method and laser construction depth meter method.The test re-sults 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 correla-tion coefficient reached 0.97,indicating that the two method has good accuracy in detecting asphalt pavement construction depth.
