The structural diseases of the airport runway pavement seriously threaten the operation safety of aircraft. In order to accurately and timely detect the capacity of the pavement structure and identify the internal structural diseases, this paper relies on Harbin Airport to carry out nondestructive testing technology research on runway pavement structural conditions. The Heavy Weight Deflectometer (HWD) is used to comprehensively evaluate the bearing capacity of the airfield pavement, and the Ground Penetrating Radar (GPR) technology is used to detect the internal diseases of the pavement structure layer. The results of nondestructive detection show that the bearing capacity of the runway pavement shows a downward trend, and the hidden disease is mainly the separation between the cement concrete layer and the base layer. Also, disease detection and treatment provide accurate and reliable technical basis.
