21-3 Development of Cost-Effective Rapid-Setting Concrete for Improved Bridge Joint Performance

Project Dates: Jul 1, 2021 - Sept 30, 2023
Project Description:

While Accelerated Bridge Construction (ABC) projects enjoy high material quality due to a large fraction of precast and prefabricated elements, connections between these elements must be placed in-situ. These are often treated as a "weak-link" in the ABC approach due to potential risk for inferior performance. VTrans has adopted the use of rapid-setting concrete (RSC) for construction of connections between precast elements in ABC. Current VTrans practice dictates use of a membrane and overlay on ABC projects due to concerns of poor durability of RSC in ABC connections. There is an urgent need to assess RSC materials designed using the current VTrans special provisions with respect to their durability and structural capactity and propose non-proprietary mix designs or proportion limits that may be adopted by VTrans for RSC to be used in ABC connections.
