• Abstract:
  Durable, reliable infrastructure is vital for local, state, and national economic growth and development. As the economy grows, so too do the demands placed on existing infrastructure, notably on roads and bridges. To keep up with the ever-increasing demand, new, durable, rapidly erected bridges are needed. Increasingly, these bridges utilize new materials and construction techniques to improve durability, reduce construction costs, and speed erection. To respond to this need, the University of Maine developed a novel, fiber reinforced polymer (FRP) tub girder (referred to as a “CT girder”) for use in new bridge construction as an alternative to conventional steel and prestressed concrete structural members (Dagher et al. 2019; Davids et al 2022a, 2022b; Davids & Schanck 2022). CT girders have been identified as a promising technology to support sustainable and durable infrastructure development, as they are comparatively light and overcome many of the challenges associated with precast NEXT beam concrete structures by reducing shipping costs and camber variability caused by prestressing. Commercialization of this technology is underway, with the evaluation of the first CT girder bridge constructed for regular traffic, the Hampden Grist Mill Bridge (HGMB) completed (Davids and Schanck 2022), two more bridges to be completed this year, and other bridges in the design or pre-construction stage.
