Air-Launched GPR Evaluation for Rapid Assessment of MoDOT Bridge Decks

The overarching goal of this study is to demonstrate that advanced nondestructive testing/evaluation (NDT/NDE) techniques can be rapidly, effectively, and economically implemented as part of routine Missouri Department of Transportation (MoDOT) bridge deck surveys to determine the general condition of bridge decks. This study extends the work of a separate study (Nondestructive Evaluation of MoDOT Bridge Decks - Pilot Study, MoDOT Award TRyy1308) focused on NDT/NDE techniques for comprehensive bridge deck assessment. It is envisioned that the condition assessment conducted in the present study will be utilized as reconnaissance to identify and rank those bridges requiring a more detailed investigation, which will enable MoDOT to optimize the use of resources and reduce the cost of bridge deck evaluation. Results of this study will be used to evaluate the feasibility of a large scale, long-term program (multi-year, routine basis) that incorporates NDE techniques into MoDOT bridge deck surveys for the purpose of reducing cost on assessment and maintenance of bridge decks.
