In Texas, two overpasses have been constructed with high-performance concrete (HPC) in projects sponsored by the Federal Highway Administration (FHWA) and the Texas Department of Transportation (TxDOT), in cooperation with the Center for Transportation Research at the University of Texas at Austin (UT). Using the knowledge gained from the first two projects, the UT researchers and TxDOT personnel developed a durability specification for bridge decks and substructures. Several bridge construction contracts with normal strength HPC decks have incorporated the new durability specification, and more are planned. The durability specification will be updated as research and implementation continue.
