Typical Disease Detection of Asphalt Pavement on Xiangjing Expressway Using 3D Ground Penetrating Radar
Due to long-term traffic load,groundwater subsidence and the impact of the natural environment,high-speed road disease problems occur from time to time,seriously affecting the safety of vehicle travel.Traditional inspection and maintenance means due to the long construction period,slow traffic recovery,high costs problems have been difficult to meet the current demand for testing.As an emerging inspection method,3D ground-penetrating radar is nondestructive,fast and efficient,and can effectively avoid the drawbacks of traditional inspection.This paper is based on engineering examples of Xiangjing expressway,based on three-dimensional ground-penetrating radar waveform characteristics to identify the category of disease,and analysis of detection results,the typical disease radar images of high-speed roads to summarize and summarize,to provide reference for high-speed road maintenance decisions.
