BEHAVIOR OF CONCRETE BRIDGE DECKS AND SLABS REINFORCED WITH EPOXY COATED STEEL. FINAL REPORT

Thirty-four slab specimens with splices and transverse steel were tested in the laboratory to evaluate the structural performance of concrete bridge decks reinforced epoxy-coated steel subjected to fatigue loading. Thirty specimens were tested under fatigue loading, and four were tested monotonically. Evaluations were made by comparing the performance of uncoated specimens with epoxy-coated specimens under service and ultimate load conditions. In addition, a field evaluation of six bridges was conducted to assess the in-service condition of concrete bridge decks reinforced with epoxy-coated steel in Indiana. The laboratory results indicated fewer but wider cracks in specimens with epoxy-coated reinforcement. No significant differences in the first cracking load were found between uncoated specimens and epoxy-coated specimens. The splitting crack load and failure load were lower for epoxy coated specimens. Deflections of epoxy-coated specimens were larger. The differences in crack width and deflection were reduced with repeated loading. The average bond ratios were 0.78 and 0.75 for repeated loading test. No sign of corrosion was found for the steel extracted from coring samples in the six bridges evaluated. Evaluation of the field data and samples revealed that the combination of adequate concrete cover and epoxy coating has provided a good corrosion protection. This evaluation included the first bridge in Indiana where epoxy coated reinforcement had been placed (circa 1976).
