Expectations for HPC Bridges

Abstract

This paper describes how the Texas Department o f Transportation (TxDOT) is promoting the use of high performance concrete (HPC) through research, construction, and technology transfer. The first two federally funded HPC bridge research projects, which resulted in the construction of the Louetta Road overpass in Houston and the San Angelo U.S. 67 bridge have increased the knowledge of how to use HPC. The authors have modified our statewide specifications to make use of higher strength HPC beams, and they are evaluating specification requirements for improved durability of conventional strength, cast-in-place HPC in current projects. With HPC, the authors anticipate being able to build bridges faster, thus, reducing traffic disruption.
