Abstract:

The goal of this project was to develop, investigate, and implement optimized concrete mixtures to be used in closure pour connections between precast elements in side-by-side accelerated bridge construction (ABC) superstructure systems. This project involves the use of innovative materials and mixture proportions that are intended to provide high early strengths to facilitate accelerated bridge construction, while ensuring that good long-term durability is also achieved. Mixtures including rapid-setting, fiber-reinforced concrete (RSFRC) and ultra-high-performance concrete (UHPC) were developed by the Performing Agency and evaluated in the laboratory (materials and full-scale structural testing) and on outdoor exposures to fully characterize the critical fresh, hardened, structural, and durability properties that are need for closure pour connections. Based on the findings of the literature review and laboratory/exposure site tests, candidate UHPC mixtures were selected for full-scale structural testing. By developing a wide range of mixtures with varying rheological properties, strength gain characteristics, and toughness values, the Performing Agency developed a suite of mixtures from which TxDOT may select for any given closure pour connection, thereby increasing the potential reach and impact of this project’s findings. Lastly, ABC projects in Amarillo and Bryan districts were evaluated and monitored during the course of the project.
