Development of Non-Proprietary Ultra-High Performance Concrete (UHPC) Prestressed Bridge Girders
Bridge girders made of ultra-high-performance concrete (UHPC) allow for members with shallower depths to achieve longer spans as well as reduced substructure and grading costs while still achieving required under-bridge clearances. Additionally, bridge service lives are extended due to the reduced permeability and increased tensile strength of UHPC. This project focuses on identifying and eliminating barriers to the development and implementation of precast, prestressed concrete bridge girders in Minnesota and Wisconsin using non-proprietary UHPC made of local material resources.
