New HPC Deck Girder Bridge System: Fabrication, Construction, and Behavior

The paper presents the findings of an ongoing research project that was funded by the North Carolina Department of Transportation and the Federal Highway Administration through the Innovative Bridge Research and Construction program. The focus of the paper is on a new high performance concrete deck girder bridge system fabricated using prestressed AASHTO Type III girders manufactured with an integral deck, a shape never used before in bridge construction. Analytical and experimental studies were conducted to evaluate: deck girder connections, diaphragm details, deck girder fabrication, bridge construction, and bridge behavior. This new system greatly accelerated bridge construction time, while the fabrication required only minor modifications to existing forms. Preliminary results from the bridge load test indicate that the behavior of the structure can be adequately predicted using available design and analysis tools.
