Ultra-high performance concrete (UHPC) can be used to create simple, strong, long-lasting connections needed for successful construction using prefabricated bridge elements (PBEs). Compared to many solutions in current use, UHPC allows for small, simple-to-construct connections that require less volume of field-cast concrete and do not require post-tensioning. The mechanical properties of UHPC also allow for redesign of common connection details in ways that promote both ease and speed of construction. This makes using prefabricated bridge elements simpler and more effective.
As part of the Every Day Counts Program, the Federal Highway Administrations Center for Accelerating Innovation is hosting a webinar on July 11, 2017 at 10 am (PST) on Ultra-High Performance Concrete for Prefabricated Bridge Element Connections: Implementation Stories. This webinar will provide an overview of why and how some agencies adopted the UHPC technology as part of their Accelerated Bridge Construction practice. Information will be provided about why UHPC was chosen for connections, initial projects, and full implementation along with the challenges, lessons learned and ideas for future direction.
