• 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.
