The Federal Outlook for High Strength Concrete Bridges

Considerable research has been conducted during the last 20 years on high strength concrete materials, mix proportions and basic properties. Some research has also been conducted during this time span on its capacity for use in bridge members. However, structural questions remain. Also, very little has been done regarding the implementation of high strength concrete bridges. This paper will document the use of high strength concrete in bridges and present bridge design concerns. Additionally, it will present significant research results and ongoing research programs, as well as highlight remaining areas for future research. It should be noted that the contents of this paper reflect the views of the authors and do not necessarily reflect the official views or policies of the Federal Highway Administration or any other federal agency.
