Due to the influence of construction quality, material aging, uneven settlement of foundation and other factors, cracks and water accumulation often occur in the road structure layer. The accumulated water will directly affect the overall quality, service life and normal functions of roads, and adversely affect the integrity, stability and driving safety of pavement structures. In this paper, based on the characteristics of high efficiency and nondestructive detection by ground penetrating radar, and relying on an actual road project in Anyuan County, Ganzhou City, and based on theoretical analysis, it is proposed to use ground penetrating radar to obtain measured data to estimate the water content of road structure. The application and research status of ground penetrating radar detection technology at home and abroad were analyzed. Based on Maxwell basic equation, the basic principle and field detection technology of ground penetrating radar were analyzed. Based on the actual road engineering, the water content of road structure layer was estimated theoretically and verified by core drilling. The results show that it is feasible to estimate the water content of road structure layer by using ground penetrating radar, which can provide relevant reference for nondestructive testing of road structure.
