• Abstract:
  Durable, reliable infrastructure is paramount to local, state, and national economic growth and development. As these economies continue to grow, 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 and in turn require the use of new materials and construction techniques to supersede more conventional, less durable designs. 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. 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. To improve on this system, AIT Bridges, the firm that designs and manufactures FRP bridges and bridge components, and to whom the University of Maine licenses the CT girder system, has proposed connecting two CT girders with a partial precast concrete deck into a new, composite section.
