Innovative Field Cast UHPC Joints for Precast Bridge Decks. Design, Prototype Testing and Projects
Bridge owners are frequently faced with the need to replace critical bridge components during strictly limited or overnight road closure periods. This chapter presents the development, testing and installation of several projects utilizing precast high performance concrete (HPC) bridge elements with field cast ultra high performance concrete (UHPC) joint fill. By utilizing UHPC's unique combination of superior properties in conjunction with precast bridge deck panels, bridge design is advanced. Direct benefits include: improved bridge deck performance through the reduction of joint size and complexity; improved continuity and speed of construction; and elimination of field post‐tensioning. Indirect benefits include: improved durability; lower maintenance; and extended usage life.
