The main objective of the conducted research was to evaluate 3D-Radar GPR in bridge deck condition assessment and imaging, with an emphasis on detection and characterization of corrosion induced bridge deck delamination. A broader objective of the study was to provide data for comparative evaluation of the performance of 3-D Radar, PERES (Precision Electromagnetic Roadway Evaluation System) GPR and other nondestructive (NDT) technologies in NDE bridge deck evaluation. The main task of this project was to provide comparative field evaluation of the 3D-GPR and impact echo (IE) technique in delamination detection and characterization.
