Strategies for Strengthening Highway Construction Testing and Quality Control

In recent years,the scale of China’s highway projects have been expanding.However,in real life,road construction projects in some places have not passed professional and rigorous inspections,resulting in various quality problems,and seriously affecting the safety of drivers and pedestrians.This paper analyzes the current situation of highway engineering test and detection,expounds the application of new technologies for highway engineering test and detection.In this paper,a case study was carried out on ground penetrating radar(GPR),which aims to improve highway engineering test and detection and provide reference for reducing highway safety risks.

Application Strategy of CBR Test in Highway Engineering

California Bearing Ratio(CBR)test is highly professional and requires a high level of skills.In order to improve the accuracy of the test results,the relevant staff will not only need to understand the rules and procedures involved in the test,they would also need to be meticulous in their work to avoid human errors,provide good data support for highway engineering,and improve the overall quality of the project.Therefore,this paper presents an analysis of the application of CBR test in highway engineering,which can provide reference for engineering and promote the development of the highway industry.
