Abstract

Bridge owners are frequently faced with the need to replace critical bridge components during strictly limited or overnight road closure periods. This paper presents the development, testing and installation of several projects utilizing precast 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. Benefits include: improved bridge deck performance through the reduction of joint size and complexity, improved durability, improved continuity, speed of construction, elimination of post-tensioning and extended usage life.
