Analysis on the Application of Field Testing Technology for Cement Concrete Pavement Strength
As the core structure of road engineering, the strength performance of cement concrete pavement has a direct impact on the pavement bearing capacity, service life, and driving safety after later operations. This study combines the actual construction and operation needs of road engineering sites to conduct systematic research on three mainstream on-site testing technologies for concrete pavement strength. These techniques are the rebound method, ultrasonic rebound comprehensive method, and core drilling method. The purpose is to accurately grasp the physical quality of the road surface and effectively identify structural hazards. After expounding the core purpose and specification requirements of strength testing, this paper analyzes the working principle, supporting equipment, operation steps, and core technical points of the three technologies one by one. This paper also compares the parameters of the three technologies, so as to highly clarify the applicability of the technologies under different working conditions.
