Abstract:

This study explored the feasibility and acceptability of using stay in-place fiberglass reinforced plastic (FRP) jackets and underwater steel reinforced grout for timely bridge piling repairs in Minnesota without dewatering. One of the goals of the project was to determine the current state of practice to this corrosion repair and inspection by researching other projects using similar repairs and to develop a survey to other departments of transportation to gather their experience with this type of repair. Another goal was to document the entire repair process on bridge 9462. Two different products, Five Star PileForm F Jacket and grout system and Denso SeaShield FX-70 and grout system were installed, and contractor feedback was collected during the installation. This type of repair had a very limited impact to the surrounding area compared to a cofferdam-type repair. In fact, the repair was practically invisible to the drivers on the bridge and boaters were able to pass under the bridge while repairs were taking place. The contractor preferred the Denso product due to the jacket being stiffer, which made the jacket want to shut, since visibility in the water was zero. The jacket’s seam was easier to line up. Both products had identical installation steps, and both seemed to be a viable alternative to bridge pile repairs based on the performances from other projects found during the research.
