Lighter weight decking has emerged as a growing requirement for truss bridges which are used for pedestrian walkways and bicycle paths.
“By incorporating a lighter weight bridge deck with a truss superstructure and fencing, contractors can assemble the bridge near the work site and lift it into place over busy roads with a minimum of road closure time,” says Scott Reeve, president and CEO for Composite Advantage, Dayton, Ohio, USA.
“Depending on bridge span lengths, FRP decking can save up to 100,000 lbs per span. This kind of weight savings means faster bridge erection using lighter cranes.”
Composite Advantage has established standard fibre reinforced plastic (FRP) bridge deck configurations based on AASHTO pedestrian bridge requirements and typical stringer support spacing. Bridge deck depths include 3, 3.5, 4 and 5 in. These product forms and depths will provide designers with the specifications they need to incorporate FiberSPAN decking into their bridge concepts.
Composite Advantage is also able to provide additional deck configurations and depths to help engineers optimise bridge designs. The bridge deck product comes with a non-slip wear surface. Standard colours include gray and beige and custom colours are available. Curbs, drainage scuppers and expansion joints are optional features that can further reduce on-site construction time and labour.
