The U.S. highway transportation infrastructure is currently facing many challenges. One emerging solution is the use of ultra-high performance concrete (UHPC) to create resilient structures through enhanced mechanical and durability properties. The Federal Highway Administration (FHWA) has been investigating the use of UHPC in the transportation infrastructure since 2001 and has made major strides in introducing the concrete and transportation industries to this next generation of concrete technology.
The decade of progress in the U.S. has provided a strong foundation on which to build. States around the country are beginning to consider UHPC solutions, with great interest being focused on the use of field-cast UHPC as a connecting element between prefabricated bridge elements. Design procedures are being developed and test methods are being devised. Twenty bridges with UHPC components are currently in service in the U.S. highway transportation system. The future promise of UHPC-class materials is beginning to be realized today.
