According to the 2009 Report Card for America’s Infrastructure, one in four of the nation’s bridges are listed as structurally deficient of functionally obsolete, establishing a dire need for new and innovative repair and replacement techniques to improvethe efficiency and state of the nation’s bridges.Full-depth pre-cast bridge deck panels have proven to be a rapid, efficient and cost effective solution to cast-in-place bridge deck replacement techniques. However, the panel-to-panel connection for these segmental deck replacement systems requires further development and testing to improve their structural redundancy, and to streamline their installation procedure. Multiple transverse joint configurations have been developed, fabricated, and tested in order to evaluate their shear transfer capabilities and ease of use. It was determined that a round corrugated transverse joint configuration provided the greatest shear transfer capacity and an efficient installation procedure.
