|Abstract: ||The deterioration of transportation facilities has become a major concern in todayâs society due to their age and increased use. Many existing bridges require rehabilitation to their concrete bridge decks and even new bridges will require repair or replacement within fourteen years of construction. These conditions are the result of the use of steel reinforcement in the concrete, which despite its high strength, ductility, low cost, and availability, is highly susceptible to corrosion. The need to provide a non-corrosive reinforcement which provides the same structural stability as steel is great and although alternatives have been tried, one has yet to prove itself as a worthy replacement for steel.
One such bridge deck that exhibits these deteriorated conditions is the elevated portion of Pennsylvania S.R. 0095 (Interstate 95), segment 0300. To improve its condition for long term performance, we intend to show that the use of ductile-hybrid fiber reinforced polymer (D-H-FRP) reinforcement will extend the life of the bridge deck, increase its durability, improving its safety and ultimately act as a feasible, structurally sound alternative to steel reinforcement. D-H-FRP rebar is a composite material currently in development at Drexel University and exhibits ductility and strength characteristics similar to those of steel which is unlike any other commercially available FRPs. Once experimental verification has been completed to check the validity of this new product, the obtained material properties of the rebar will be used to complete a replacement design of the I-95 bridge deck using this H-H-FRP composite rebar.|
