Abstract:

The objective of this project was to investigate the performance of the ultrahigh performance concrete (UHPC) closure joint reinforced with noncontact lap-spliced reinforcing steel bar, with a specific focus on determining when a noncontact lap splice has sufficient strength to either open a bridge or expose it to construction loading. In addition, the research was conducted to explore and compare an alternative material, hybrid composite synthetic concrete (HCSC), that may be able to provide sufficient early-age capacity at less overall cost than UHPC when used as the closure-joint material.
