States are considered deficient. The deterioration of the
concrete components is a leading cause of the problem.
The deterioration of concrete bridge decks is due primarily
to corrosion of the reinforcing steel in the concrete. A
promising solution to the problem is the use of fiber
reinforced plastics (FRP) as a replacement for reinforcing
steel. The use of FRP as reinforcement has the following
advantages of lightweight, high tensile strength, corrosion
resistance, flexibility, and electromagnetic resistance. This
paper looks at the use of FRP as reinforcement in concrete
beams and compares the information from deflection
measurements of different configurations. Also, a material
cost comparison is made to determine the cost of using the
FRP reinforcement over standard steel reinforcement.
Concrete bridge deck systems are designed using steel and
fiber-reinforced plastics and allowable stress and load
resistance factor methods. Recommendations for further
study and uses of FRP are made.
