This investigation was a component of the Innovative Bridge Research and Construction (IBRC) Program that was authorized by Congress in the Transportation Equity Act for the 21st Century (TEA-21) legislation. The project objective was to evaluate and provide a historical record of approved State bridge construction projects throughout the United States that employed corrosion-resistant reinforcement. The study involved site visits, documentation of attributes and any problems associated with the various reinforcement types, and acquisition and testing of reinforcement samples.
