The strategic plan for bridge engineering issued by AASHTO in 2005 identified material deterioration as one of the primary challenges to achieving extended life. In substructural applications, construction materials such as steel and concrete are subjected to deterioration. Ultra High Performance Concrete (UHPC) has a compressive strength of 26,000 psi (180 MPa) and excellent durability, and this study explores the possibility of using precast, prestressed UHPC piles. An H-shaped UHPC section, which is 10-in. (250-mm) deep, was designed for constructability and economical reasons. Instrumented UHPC elements were cast to conduct large-scale field tests. In the field, two UHPC piles have been successfully driven in glacial till clay soil and tested under vertical and lateral loads. Test results, durability, drivability, and other material advantages over normal concrete and steel indicate that UHPC piles are a viable alternative to extend the life of bridge structures.
