Composite designs are available for demanding civil applications including traffic bridges, pedestrian bridges, rail platforms, transit shelters, buildings, wall panels, access mats, barriers, utility vaults, and trench covers, as some examples. Harsh outdoor conditions, and road salt have no effect on composite products making them a superior choice for these civil applications.
In the case of many structures, the deadload weight can be reduced to improve overall capacity and provide a more efficient design. Increased lifespan, and reduced maintenance costs add to the long term value. Many structures can now provide 100+ years of design life with minimal upkeep.
