Use of Fiber Reinforced Concrete in Bridge Approach Slabs
Bridge approach slabs are deteriorating at a much faster rate than expected resulting in a massive need for repairs and premature replacement costing millions of dollars annually. Both environmental and traffic loading causes the concrete to worsen which accelerates the deterioration process by allowing deleterious agents to enter the concrete. In order to enhance the service life of bridge approach slabs the material needs to comply with certain performance criteria such as crack resistance, durability enhancement and post crack flexural stiffness. A Hybrid Fiber Reinforced Concrete (HyFRC) was developed for the use in bridge approach slabs in Area III jurisdiction which are exposed to severe environmental conditions. Deflection hardening was used as a performance goal in the design of the HyFRC composite.
