Repairing Steel Girder End Corrosion Using Ultra-High Performance Concrete

This paper presents a case study of using ultra-high-performance concrete (UHPC) to repair a large steel highway bridge severely damaged by corrosion at the plate girder ends and the steel rocker bearings. In addition to fixing the corrosion issues at the girder ends, the use of UHPC also enabled the jacking of the superstructure to allow rocker bearing repairs. Due to limitations posed by the bridge height and location, the surrounding...
