Repair and Upgrade of Steel Culverts Using Sprayable Ultra High Performance Concrete (UHPC)

This research proposes using Ultra-High-Performance Concrete (UHPC) shotcrete to repair and upgrade steel culverts, addressing significant infrastructure challenges posed by aging, deterioration, and increased traffic demands. Many U.S. steel culverts are nearing the end of their service life, suffering from corrosion, wear, and soil erosion, which can lead to structural failure and severe environmental and economic consequences. This study aims to optimize UHPC shotcrete mixtures, evaluate their mechanical and durability properties, and assess their effectiveness in repairing and upgrading steel culverts.
