2313 Design and Monitoring of Non-Proprietary UHPC Joints of Precast Elements

The purpose of this study is to take the results of the 2276 study entitled “Evaluation of Ultra-High Performance Concrete for Use in Bridge Connections and Repair” and implement and monitor the effects of the UHPC process on various bridge deck joints throughout the state. Deterioration of bridges can often be related to poor performance of longitudinal connections between precast members or transverse deck joints. Ultra-high performance concrete (UHPC) is a cementitious composite with mechanical and durability properties far exceeding those of conventional concrete, which makes it an ideal material for bridge deck joints. UHPC is a relatively expensive material and is most economical when use of a small quantity can have a large impact on overall performance of a structure.
