Abstract
It is important to find out the locations and grades of asphalt overlay debonding on runway for airfield pavement maintenance and the flight safety.In this paper,using GPRMax2D based on the method of the finite difference time domain method (FDTD),simulating the ground penetrating radar (GPR)reflection profiles characteristics from debonded locations. According to the comparative analysis with numerical simulation data,GPR survey profile and drilling datum,establishes an in-terpretation classification model of asphalt overlay debonding,that results of inference and interpretation based on the GPR method with a reasonable accuracy and high reliability,is a rapid,nondestructive,reliable technology can be used for detecting asphalt overlay debonding on runway.关键词
