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.

    Innovations in drilling and blasting and crushing and screening are bringing major economies of scale to aggregate production operations. Drilling and blasting is an area where new technology is offering major saving to quarrying companies. This is another important factor in the quarrying process, as inefficient drilling and blasting can have major financial repercussions.

    For environmental reasons planners decided in favour of the challenging task of constructing a 13-field arched highway bridge over the Oparno Valley in the Bohemian area of the Czech Republic. The 258m bridge, whose reinforced concrete arch has a span of 135m, straddles the valley without any bridge piers, transferring the loads in the form of compressive forces into the foundations.

    Modern technology is making testing more efficient and reliable, increasing productivity and reducing costs, as Patrick Smith reports A few years ago, visual inspection of an 18-year-old bridge by ARRB in Australia identified considerable cracking in the precast, prestressed deck planks as well as in the cast in situ deck overlay. Laboratory examination indicated that the deck planks and the deck overlay were suffering from a strong case of alkali-aggregate reaction (AAR). Testing of concrete cores drilled
