Positive field outcomes have compelled federal and state transportation officials to acknowledge UHPC con- nections' more recent role in advancing the use of precast for accel- erated bridge construction. connection details in ways that promote ease and speed of construc- tion, making PBE connections simpler and more effective. Transportation agencies are exploring various uses of UHPC to improve bridge projects. The Delaware Department of Transportation, for example, completed the nation's second bridge deck overlay using UHPC on the Blackbird Station Road project in New Castle County. The project showed the material's suitability to connection details that make PBEs simpler and more effective for accelerated bridge construction. DelDOT also used UHPC to connect the adjacent box girders on the structure, which received Accelerated Innovation Deployment Demonstration funds. The Illinois Department of Transportation is using prefabricated deck panels with UHPC connections on an AID Demonstration project to reconstruct the Campground Road Bridge over Interstate 57 in Jefferson County. The bridge will have increased load-carrying capacity and enhance safety by providing a wider road- way and more clearance over the interstate. The Iowa Department of Transportation is the lead state on a pooled fund research project to develop a UHPC structural design guide. In late 2017, the agency published new standards for adjacent box girders, including material and construction specifications for UHPC. The New Mexico Department of Transportation is monitoring the performance of a UHPC girder bridge and designing another four projects that will use the material for connecting PBEs. NMDOT is also conducting research on UHPC bridge deck overlays and applying State Transportation Innovation Council Incentive funds to develop an overlay mix design using local materials for UHPC to integrate into specifications.
