Thirty-four slab specimens of two types of cross section with splices and transverse steel were tested to evaluate the structural performance of concrete bridge decks and slabs with epoxy-coated reinforcement and subjected to repeated loading. Evaluations were made by comparing the performance of specimens with uncoated bars to that of otherwise identical companion specimens with epoxy-coated bars under repeated loading and at ultimate load condition. Test variables included concrete compressive strength, bar size and deformation pattern, coating thickness, splice length, and applied stresses. During the repeated loading portion of the tests, specimens with epoxy-coated reinforcement had fewer but wider cracks than those with black reinforcement, while differences in deflections were not significant. At failure, average bond stress ratios were 0.78 with #7 bars and 0.75 wilh #11 bars. The strength results support the use of a single development length modification factor for beams with spliced epoxy-coated reinforcement.
