Determination of Bridge Deck Subsurface Anomalies by Infrared Thermography and Ground Penetrating Radar; Polk-Quincy Viaduct I-70, Topecka, Kansas
The purpose of this study was to evaluate the use of infrared (IR) theromgraphy and ground penetrating radar (GPR) to find subsurface anomalies, delaminations and de-bonding, on asphalt concrete overlaid concrete bridge decks. An infrared thermographic and ground penetrating radar evaluation was conducted on the I-70 Polk-Quincy viaduct in 1993. The results were compared to other studies conducted to check for subsurface anomalies. These included a 1989 Geology bridge deck evaluation, completed before the membrane and overlay were in place, a 1992 membrane-pavement system electrical resistivity study, and a 1996 Research evalaution to check for de-bonding. The last two studies were completed after the asphalt concrete overlay was in place. There were differences between the results of the IR/GPR study and those conducted using the more traditional methods.
