Development of Innovative Two-Layered System for Upgrade of Steel Culverts (UHPC Shotcrete + Sprayable Self-Healing Concrete)

This research proposes using Ultra-High-Performance Concrete (UHPC) shotcrete combined with sprayable self-healing concrete to upgrade steel culverts, addressing challenges related to aging, deterioration, and increased traffic. An accompanying project will also be carried out at Innovative Bridge Technologies/Accelerated Bridge Construction University Transportation Center (IBT/ABC-UTC) that will be complementing this project. Overall, the research results will accomplish the project vision and objectives. Many U.S. steel culverts are approaching the end of their service life due to corrosion, wear, and soil erosion, which can result in structural failure and significant environmental and economic impacts. This study aims to optimize effectiveness of sprayable UHPC by applying self-healing concrete mixtures, evaluate their mechanical and durability properties, and assess their combined performance when applied to steel culverts.
