Abstract:Conventionally, highway bridge decks in the US are predominantly made of steel-reinforced concrete. However, repair and
maintenance costs of these bridges incurred at the federal and state levels are overwhelming. As a result, for many years, there
has been pressure on transportation agencies to fi nd new cost-eff ective and reliable construction materials. A very promising
alternative is the fi ber reinforced polymer (FRP) bridge deck system. FRP composites have found increasing applications in bridge
design and construction. Light weight, high strength and stiff ness, durability, and ease of construction are major advantages of
FRP material. Meanwhile, issues such as high initial construction cost, lack of design guidelines or standards, and the materials’
sensitivity to ultraviolet radiation, etc. do still stand against FRP’s widespread application.
