Evaluation of Pavement System Based on Ground-Penetrating Radar Full-Waveform Simulation

The purpose of this study is to extend the use of ground-penetrating radar (GPR) methodology toward a more reliable and accurate interpretation of pavement conditions. With the electromagnetic Green's function for a layered system with a horizontal electric dipole, the GPR scan can be simulated over a wide range of pavement profiles. Examples are provided for GPR simulation on a three-layer pavement system. With forward model, the best match of...
