Deployment of prefabricated concrete bridge decking systems continues to face constructability and serviceability challenges related to the field-cast connections between the components. A set of connection details was developed, tested, and brought to initial deployment. These details engage the performance of ultra-high-performance concrete (UHPC) to afford simple connections with minimal field fit-up concerns, reduced aesthetic and ridability concerns, and an expectation of enhanced durability. Bridge deck�? level connection details that allow for the noncontact lap splicing of no. 5 (16M) reinforcing bars within less than 6 in. (150 mm) were successfully tested under a range of structural loadings. Composite connection details that facilitate simplified construction by eliminating the need for interlacing the discrete connectors and pockets in adjacent girders and deck elements were also tested under cyclic and static loadings. The UHPC connections were found todisplay performances that equalled or superseded that of conventional systems.
