  • Abstract:
    Fiber reinforced polymer (FRP) honeycomb panels offer an efficient and rapid replacement to ; concrete decks. The system consists of FRP honeycomb sandwich panels with adequate guardrails. Although ; FRP bridge deck panels have already been designed and used over the past several years on a number of ; through truss bridges, they could not be used on steel girder bridges until approved crashworthy bridge ; railing attachments could be validated. Two systems have been successfully crash tested, one with steel thrie ; beams/guardrails on steel posts and the other with concrete barriers. Both systems are now ready for use on ; temporary/detour bridges, or as permanent deck replacement allowing higher live load while keeping the ; existing steel girders and substructure. ; The light weight of FRP honeycomb panels (about 75% lighter than concrete) allows heavier truck ; loads, while keeping the existing girders and substructure without compromising the safety of the public. The ; roadway can be made wider by increasing the overhangs, thus allowing for wider farm equipment on narrow ; bridges in rural areas. The replacement of the concrete deck using this system may be completed in a matter ; of a few days, or even hours, as opposed to several months when using the conventional methods.
