Use of Ground Penetrating Radar to Delineate Bridge Deck Repair Areas
Ground penetrating radar (GPR) has emerged as a viable means of nondestructively determining the locations of deteriorated sections of bituminous-overlaid, reinforced concrete bridge decks. While prior GPR successes on such structures were traditionally limited to estimating repair quantities and had not been shown to consistently provide an accurate indication of the location of distressed areas, work conducted in 1998 and 1999 on several New Hampshire bridges produced predictions of deterioration that compared favorably with ground truth data and conventional (destructive) survey techniques. Recent development in GPR technology provided high resolution images of the bridge deck structure that were used to create contour maps detailing different levels of deterioration. This report summarizes efforts initiated and sponsored by the New Hampshire Department of Transportation (NHDOT) related to location-specific predictions of corrosion and freeze/thaw induced deterioration on existing bridge decks scheduled for rehabilitation.
