Prescribing a Bridge Deck Ride Quality Repair Using the South Dakota Road Profiler and the Dipstick: Technical Assistance Report
Kevin K. McGhee
Year: 1996
VTRC No.: 97-TAR2
Abstract: This report describes how two sophisticated road roughness instruments were used to investigate the feasibility of a bridge deck ride quality repair. The instruments were the South Dakota Road Profiler (SDRP) and the Face Companies' Dipstick®. The bridge being repaired was on Interstate 95 over the Occoquan River in Northern Virginia. The repair being considered was a strategic grinding of the surface to remove high spots in the concrete. In addition to a badly formed profile, the top steel over much of the deck suffered from insufficient concrete cover. Using the SDRP and the Dipstick®, a research team was able to provide detailed illustrations of the repair strategy necessary to mitigate the significant rideability problem without exposing steel. Using the same equipment, this team was able to objectively monitor the progress and eventual success of the repair.
