Abstract:
Extensive accelerated aging tests were conducted on polymer composite bars reinforced with aramid (Technora®) fibers. Aramid fiber-reinforced polymer (AFRP) bars exhibited desirable durability characteristics under a broad range of accelerated weathering effects. They also exhibited satisfactory bond strength and dowel action in concrete. A bridge deck reinforced with AFRP bars was designed with due consideration given to the punching shear mode of failure. The design procedures were verified through scaled laboratory tests. The bridge deck reinforced with AFRP bars was constructed in Michigan. The construction and cost attributes of aramid FRPs were evaluated in this field project.
