- Resumen:
In 2009, a detailed survey was performed on six bridge decks in West Virginia, which were among the earliest applications of epoxy-coated reinforcement. The purpose was to examine the long-term field performance of epoxy-coated reinforcing bars. The survey comprised visual inspection, sounding for delamination, crack mapping and crack width measurements, cover depth measurements, and coring. The corrosion state of bar samples removed in cores was examined as well as bond between the epoxy coating and steel and coating thickness. Chloride profiles from concrete cores were also obtained. Overall, the epoxy-coated reinforcing bars were in excellent condition, with very little active corrosion after up to 35 years of service.
