PMSS Project Details


Project ID:FHWA-PROJ-08-0008
Project Name: Development of an Ultra-High Performance Concrete Bridge Superstructure System
Status: Completed
Last Name:Graybeal
First Name:Benjamin A (Ben)
Office: Office of Infrastructure Research and Development
Team:Bridge and Foundation Engineering Team
Roadmap/Focus area(s): Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:This project developed and refined an optimized component that combined the bridge superstructure and deck into a single modular element. This prestressed Ultra-High Performance Concrete (UHPC) component meets all load requirements in the American Association of State Highway and Transportation Officials Load and Resistance Factor Design Bridge Design Specification. It facilitates accelerated construction by allowing for the construction of a bridge that is almost entirely prefabricated.
Laboratories: Structures Laboratory
Start Date: July 1, 2008
End Date: December 31, 2009
Goals:The key project objective is to develop a modular bridge girder component that engages the unique strength and durability properties of Ultra-High Performance Concrete (UHPC) to address pressing needs in the highway structure arena.
Test Methodology: Use computational modeling to develop an optimized component; fabricate full-scale components; complete full-scale structural testing of the component to verify anticipated behaviors.
Other Information: A prior study developed a prototype modular component. Further information can be found at:
