Hyperbola Occurrence in GPR Radargrams of Cracked Road Pavements: A Numerical Comparison of Top-Down and Bottom-Up Cracking

Ground-penetrating radar is widely used in non-destructive pavement evaluation, but the occurrence of multiple hyperbolic signatures in radargrams of cracked pavements remains insufficiently characterized, particularly for top-down and bottom-up cracking. This study investigates the occurrence of de...
