DOWNLOAD EBOOKThis document is a technical summary of the Federal Highway Administration (FHWA) report "Bond Behavior of Reinforcing Steel in Ultra-High Performance Concrete" (FHWA-HRT-14-090). Ultra-high performance concrete (UHPC) has garnered interest from the highway infrastructure community for its greatly enhanced mechanical and durability properties. The objective of this research is to extensively evaluate the factors that affect bond strength between deformed reinforcing bar and UHPC, and to facilitate the development of design guidelines for using field-cast UHPC in innovative connection details. The results of the research effort and the design recommendations for reinforcing bar embedded in UHPC are provided in this TechBrief.
