FRP bridge decking

Description Fiber reinforced polymers (FRP), primarily used in the aerospace industry, have started being applied to the design of bridges. FRP composites are primarily made up of fibers aligned within a resin material in such a way to make a very strong and very customizable material. The most common fiber choices are glass and carbon fibers. In the use of bridge decking, FRP have been molded into cellular panels that can be installed as full-depth deck panels. Application FRP deck panels are used as an alternative to cast-in-place concrete decks. They provide a driving surface for traffic. Constructability To connect the panels to one another, the panels are design to interlock with male-female shear keys. Another option for connecting the panels is the use of high quality epoxy adhesives. To connect the panels to the steel framing, pockets are formed over the beams to allow for welded stud shear connectors and non-shrink grout. Bolts can also be used to connect the panels to the steel framing.
