Abstract:
For the design and construction of a high-performance concrete (HPC) bridge in Sarpy County, Nebraska, the project team utilized the Federal Highway Administration definition of HPC. Because of the use of de-icing salts and high freeze/thaw cycles, the focus was to specify a durable deck concrete. The University of Nebraska’s Center for Infrastructure Research assisted in the research and verification of testing. A list of mix proportions that met project objectives were supplied to the contractor. The bridge deck was instrumented and monitored during the placement and curing process. As a result of this project, a High-Performance Concrete Strategic Plan was developed for use by the state in the future, and should lead to more durable decks.
