Abstract: UHPC has emerged as a class of materials capable of addressing a variety of shortcomings commonly encountered in the U.S. bridge sector. As with any constructed facility, bridges are recognized to be comprised of components whose performance and resiliency vary thus often necessitating preservation actions to address premature deterioration. By focusing on developing innovative solutions that address immediate needs, the weak links in the structure’s performance can be mitigated and the overall structure’s performance can be improved.
The U.S. Federal Highway Administration continues to investigate optimal uses of UHPC in the highway sector and work with partners to deploy promising solutions. Recent advancements include assessments of performance of a range of available UHPCs and the development of novel field-cast UHPC connection details. Owners across the country are becoming aware of the benefits of UHPC and are beginning to press forward with innovative solutions such as deck rehabilitation overlays, link slabs to replace joints over interior piers, and deteriorated steel girder web encasement.
