Following successful development and testing of a tapered H-shaped pile at Iowa State University in partnership with the Iowa Department of Transportation, 11.8 in. deep UHPC piles were designed and installed at the west abutment of the Lily River Detour Bridge in Highway 11, a project for the Ministry of Transportation of Ontario near Kapuskasing in Ontario, Canada. The east abutment was designed to be supported by six steel H-shaped battered piles. For the west abutment, five six UHPC piles were produced and installed using the same batter. Since the site contained occasional boulders and the design intent to drive the piles to bedrock, the UHPC piles were constructed with steel shoes. All piles were successfully installed to reach the targeted load bearing capacities. After the replacement bridge was constructed, the detour bridge was removed and the UHPC piles were extracted to examine the conditions of the piles. This presentation will provide details of the innovative design of the piles, fabrication and driving of the piles, and lessons learned from analyzing the driving data and removal of the piles.
