Multi-physics nondestructive evaluation(NDE) technologies were proposed for monitoring section-loss and breakage of strands and tendons in prestressed girders moved from an actual bridge. The primary NDE technologies include Magnetic flux(MFL), Electrical resisticity(ER), Half-cell Potential (HCP), and Linear-polarization(LPR).

Robotics-Assisted Bridge Inpection Tool (RABITTM) combines a capability of conventional non-destructive evaluation techniques for condision assessment of concrete bridge decks, including electrical resistivity (ER), ground-penetrating radar (GPR), Impact-echo (IE), ultrsonic surface waves (USW), and a high resolution digital camera. In this study, the RABITTM platform was used to evaluate delaminaitons in a concrete bridge deck in the laboratory.
