The remarkable features of Ultra-High Performance Concrete (UHPC) have been reported. Its application in bridge construction has been an active research area in recent years, attributed to its higher compressive strength, higher ductility and reduced permeability when compared with conventional concrete and even high-strength concrete. With that in mind, this study investigated the performance of UHPC stay-in-place (SIP) bridge deck panels subjected to high loads in both flexure and shear. The test matrix consisted of twelve (12) half-scale panels 4 feet long and 2 feet wide. The variable parameters that were studied included thickness (i.e., 2-in. and 3-in.) as well as non-discrete reinforcement type. The non-discrete reinforcement included conventional mild reinforcement, welded wire fabric (WWF), and no reinforcement (UHPC only). UHPC panels in the latter case were cast without minimum reinforcement, as the fibers alone are expected to bridge and restrict crack development. A control deck panel with conventional concrete was fabricated and tested to serve as a baseline for comparison.
