UHPC Decked I-Beam for Accelerated Bridge Construction

Belvidere North is the first ultra high performance concrete (UHPC) bridge in Nebraska that was bid in April 2024 and expected to be constructed in 2025. This project is a result of a collaborative research effort between the Nebraska Department of Transportation (NDOT) and University of Nebraska-Lincoln (UNL) over the last four years, which led to developing non-proprietary UHPC mixture and decked I-beam superstructure system for durable, economical, structurally efficient, and accelerated bridge construction. The uniqueness of this construction material and developed system require additional resources to document production procedures, conduct quality assurance testing, and evaluate the performance of the decked I-beams, with respect to bond, shrinkage, and creep. In addition, observations on two-stage casting of decked I-beams, post-curing thermal treatment, and handling methods need to be reported for possible improvements in future projects.
