From “Building Bridges Better – Ultra-high performance concrete creates strong, long-lasting connections,” Federal Highway Administration Center for Accelerating Innovations’ Innovator, Issue 67 … The use of ultra-high performance concrete (UHPC) to make better field-cast connections between prefabricated bridge elements (PBEs) is advancing across the United States. Transportation agencies have used the steel fiber-reinforced, portland cement-based composite material on 100-plus projects since the nation’s first bridge incorporating UHPC was completed in Iowa in 2006. Half of those structures were built after the Federal Highway Administration began encouraging deployment of UHPC connections for PBEs through Every Day Counts (EDC) in 2015.
