FHWA continues to promote the use of UHPC by bridge owners for new construction, repair, and retrofit. Updates related to UHPC will continue to be provided quarterly through this bulletin.
AASHTO Committee on Bridges and Structures Passes Ballot for Guide Specification for Structural Design with UHPC
In May 2023, the AASHTO Committee on Bridges and Structures approved a ballot to adopt a new guide specification entitled AASHTO LRFD Guide Specifications for Structural Design with Ultra-High-Performance Concrete (UHPC). These guide specifications mirror Section 5 (Concrete Structures) of the AASHTO LRFD Bridge Design Specifications and cover key aspects of structural design with UHPC. AASHTO publication of the UHPC Guide Specification is expected in the coming months. Design examples and accompanying training are being developed by FHWA; details will be shared in future bulletins.
Recordings of Previous EDC-6 Webinars
Recordings of two prior National Webinars are now available for access.
UHPC National Webinar #2-Ultra-High Performance Concrete Pumping and Spraying (Shotcrete)
The second national webinar provided agencies and practitioners unfamiliar with these UHPC placement techniques (pumping and spraying) with information on recent applications and research. The speakers included Laurent Boiron, Alain Huynh Tuong, Bill Kulish, and Atorod Azizinamini.
