Ultra High Performance Concrete Highway Bridge
Wapello County and the Iowa Department of Transportation were granted funding through the TEA-21 Innovative Bridge Construction Program (IBRC), for a project that uses ultra high performance concrete (UHPC). Plans using UHPC in the prestressed concrete beams for a bridge replacement project in Wapello County, Iowa have been prepared and construction of the first UHPC bridge in the United States has begun. The concrete beams are prestressed using 0.6 inch diameter strands and contain no mild reinforcing steel, except to provide composite action with a cast-in-place deck. The research includes testing to verify shear and flexural capacities of a 71 ft. long test beam along with shear testing of smaller beams. Discussion of the design efforts and current progress of this research project are the focus of this presentation. Currently the 71 ft. test beam and shear beams have been cast. Flexure and shear testing were successfully completed, and three 110 ft. bridge beams were cast in June and July 2005. Construction of the bridge began in August 2005 and was completed in February 2006.
