Integrating Ground-Penetrating Radar and FEM Modeling for 3-D Reconstruction and Mechanical Simulation of Road Hidden Defects in Asphalt Pavement
Ground-penetrating radar (GPR) provides a fast and nondestructive method for pavement inspection. However, reliably extracting the 3-D geometric structure of hidden voids from radar images and correlating it with structural performance remains a challenging task. This study proposes a 3-D reconstruction and mechanics f...
