HIGH-PERFORMANCE CONCRETE U-BEAM BRIDGE: FROM RESEARCH TO CONSTRUCTION

The Louetta Road Overpass on State Highway 249 in Houston, Texas, is a high-performance concrete bridge design and construction project that is sponsored by FHWA and the Texas Department of Transportation in cooperation with the Center for Transportation Research at The University of Texas at Austin. The overpass, being constructed in 1995, incorporates high-performance concrete in the precast pretensioned U-beams, the composite precast/cast-in-place deck, and the precast posttensioned substructure. Beam concrete design strengths reach 90 MPa (13,000 lb/sq in.), with 15.2-mm (0.6-in.) diameter, 1862-MPa (270-ksi) prestressing strands required to fully use the higher concrete capacity. The use of high-performance concrete in bridge construction is anticipated to be cost-effective at the time of construction and during the life of the structure. Implementing its use in bridge construction is a dynamic process that requires flexibility as new information and concerns arise. The ability of all parties involved to work as a team, with open lines of communication, is of extreme importance.
