Abstract:This report is intended for bridge owners, contractors, and their supporting professionals responsible for design, construction, materials, and maintenance who are interested in including ultra-high performance concrete (UHPC) in their bridge preservation and repair (P&R) toolkit. This document aims to familiarize the reader with the material mechanical and durability properties of UHPC, along with common and emerging UHPC-based P&R solutions. Most notably, the document contains design and construction recommendations for three promising and fastest growing UHPC P&R applications: bridge deck overlays for rehabilitation, link slabs, and steel beam end repair. These recommendations are limited in scope but provide valuable information for all owner agencies considering the development of materials, construction, and design specifications. Lastly, much of the information provided herein builds on previous UHPC design and construction documents published by the Federal Highway Administration in Design and Construction of Field-Cast UHPC Connections (Report No. FHWA-HRT-19-011).
