The 1505 American Composites Manufacturers Association (ACMA) has announced its Awards for composites excellence (ACE) at the COMPOSITES 2010 event. The awards were presented in a number of categories, with two awards gone to composite bridge structures. The most creative application award was presented to AEWC Advanced Structures & Composites Center, 1507 University of Maine, Orono, Maine, for its Bridge-in-a-Backpack, a hybrid composite-concrete bridge combining the benefits of advanced composite materials and concrete. The concept offers a cost effective, long-lasting, and easy-to-erect bridge technology. This lightweight, corrosion resistant system for short-to-medium-span bridge construction uses FRP composite arch tubes that act as a stay-in-place form, structural reinforcement, and environmental protection for concrete fill. The lightweight arches can be placed quickly by hand. The infinite possibility award was presented to 1509 Harbor Technologies, Brunswick, Maine, for its hybrid composite beam (HCB), a new structural member developed for use as a girder in bridges and other structures. This is comprised of a shell, compression reinforcement and tension reinforcement. The shell consists of a fibre reinforced polymer box beam. The compression reinforcement consists of concrete, pumped into a profiled conduit (generally an arch) within the beam shell, while carbon, glass or steel fibres anchored at the ends of the compression reinforcement provide the tension reinforcement. The HCB combines the strength and stiffness of concrete and steel with the lightweight and corrosion advantages of composite materials.

    Deck waterproofing remains critical to a bridge’s structural integrity for its design life, explains Cliff Weston, director of Stirling Lloyd To properly maintain deck waterproofing there must be a willingness to look at solutions based on whole-life costing rather than just short-term initial costs. There are lessons to be learned from examples of prematurely failed infrastructure due to a focus on initial short-term costs.

    A team of Greek and German PERI engineers have developed a comprehensive formwork and scaffolding solution for the T4 bridge on the A7 motorway in Greece. The 160km long A7 connects Kalamata in the south to Corinth in the northwest of the Peloponnese peninsula. On one stretch of the motorway a 390m long arched bridge – known as T4 – is being used to close the gap between Paradisia and Tsakona. Set for completion in early 2014, two-thirds of the 22m wide bridge superstructure will be suspended on a steel arc
