Comparison of Ground Penetrating Radar Bridge Deck Evaluation and Repair; Polk-Quincy Viaduct I-70, Topeka, Kansas
The purpose of this study was to evaluate the reproducibility and accuracy of Ground Penetrating Radar (GPR) in locating delaminations and de-bonding in asphalt concrete overlaid concrete bridge decks. The traditional 'chaining' method is a less effective option for finding subsurface defects after an overlay is in place. An infrared thermographic and ground penetrating radar evaluation was conducted on the I-70 Polk-Quincy viaduct in 1993. A second ground penetrating radar study was performed in 1997 to evaluate the condition of the bridge deck previous to removal of the existing asphalt overlay and high density concrete overlay and repair of the deteriorated deck. The results of the 1997 GPR study were compared to the results of the 1993 GPR study, the 1998 through 1999 chaining, actual repair areas and portions of the 1989 Geotechnical Unit bridge deck evaluation.
