Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   This project focuses on assessing the structural performance of deck-level ultra-high performance concrete (UHPC) connections between prefabricated concrete components. The program includes the physical testing of six unique test specimens. Cyclic and static structural loadings were applied to the test specimens, performance was monitored, and conclusions were drawn.
Goals:   Investigate the performance of ultra-high performance concrete (UHPC) when used as a field-cast grout in deck-level connections between a prefabricated bridge deck and decked girder elements. The goal is to facilitate the use of Prefabricated Bridge Elements and Systems (PBES) technology by engaging advanced cementitious materials to address specific concerns, which hinder widespread use of PBES.
Product Type:   Article
Research report
Test Methodology:   Use structural testing methods to assess performance of ultra-high performance concrete (UHPC) connections.
Other Information:   The final report has been published.
Partners:   New York State Department of Transportation; Role(s): Advisory, Other stakeholder
Expected Benefits:   This study will demonstrate the opportunities that can come from engaging UHPC-class materials as field-cast grouts in connections between prefabricated bridge elements. Ultra-high performance concrete can fundamentally change the design and construction of the connection. This study will demonstrate the performance that can be achieved when these novel connection details are deployed.
