Bridge Deck Integrity Measurements for Asset Management

Condition monitoring of transportation assets such as bridge decks is a vital component of a comprehensive asset management plan. Early detection of subsurface deterioration in bridge decks is necessary to forestall the development of dangerous conditions and to plan for repairs and replacement. Currently, non-destructive evaluation (NDE) methods applied to this problem require direct access to the bridge deck and, therefore, require closure of the lanes. The objective of this project is to develop and evaluate a NDE method that utilizes sensors placed on the underside of the bridge deck and uses active or passive noise excited from the surface to assess the condition of the deck.
