Abstract:

Vermont Agency of Transportation has adopted use of the accelerated bridge construction (ABC) approach to deliver bridge construction and reconstruction projects. While 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” due to potential risk for inferior performance and concerns of lower durability to repeated freeze-thaw cycling. The focus of this research study was to conduct a comprehensive laboratory investigation of rapid-setting concrete (RSC) materials that are commonly used for field-placed ABC connections. Further, the variations were evaluated to explore potential for hybrid performance and proportion-based specifications. The current performance-based specifications for RSC have lower risks associated with them, however, they result in higher project costs and increased laboratory and personnel resources. Assessment of durability, specifically resistance of material to degrade under repeated freezing and thawing and its ability to prevent chloride ingress were one of the focus points of this research. The results of this study indicate that currently used RSC materials have high resistance to freeze-thaw damage and ABC projects using these materials for connections can use bare decks. This research supports a hybrid performance and proportion-based RSC specification approach.
