• Abstract:
  There is a growing need for durable and resilient highway bridge construction/reconstruction systems that facilitate rapid completion of onsite activities, thus minimizing intrusion on the traveling public. Modular components can provide highquality, accelerated, and safe construction; however, offsite prefabrication of bridge components necessitates increased reliance on the performance of field-installed connections between components. The mechanical and durability responses of the grouts used in these connections are critical to the overall performance of the infrastructure system. Constructability and serviceability problems have arisen in connections on some past projects. These issues have been attributed to a variety of causes, including construction techniques, materials, and poor designs. Much attention has been placed on making better connections between components. One area of investigation relates to the different fieldcast materials that might be used to complete the connections. Selection of a grout with appropriate fresh and hardened properties is a critical step in any PBES project.
