There is a growing need for durable and resilient prefabricated bridge systems which facilitate rapid completion of on-site activities in order to minimize the impact on the travelling public. Prefabricated bridges can provide higher quality, accelerated, and safer construction; however, greater offsite prefabrications of bridge components necessitates an increased reliance on the long-term performance of field-installed connections between these components. Research on the materials between precast bridge components has emerged in the last decade. Ultra-high performance concrete (UHPC) whose mechanical and durability properties far exceed those of conventional concretes present the opportunity to significantly enhance the performance of these field-applied connections, thus facilitating the wider use of prefabricated bridge deck systems. Of particular interest here, UHPCs can exhibit exceptional bond when cast against previously cast concrete and can
