Abstract
Traditional road quality inspection is time-consuming, laborious and not highly accurate. As a new type of non-destructive detection tool, Ground Penetrating Radar (GPR) has the advantages of fast, efficient, continuous, simple and accurate operation, and is widely used. This research uses GPR to conduct non-destructive testing of cement road in a cold storage base to detect quality problems such as road diseases. Through detection, it was found that the cold storage base had no obvious cavities within 10m depth in the detection area, but there was a phenomenon of incompact and loose water accumulation. The foundation should be strengthened during construction. The thickness of the cement road was uniform, and its construction quality was good. Through on-the-spot detection, it provides reference for the ground-penetrating radar non-destructive detection of concrete roads and disaster warning.
