| Abstract: |
Current standard specification for epoxy-coated steel reinforcing bars (ASTM A775/A775M) allows coating thicknesses between 175 to 400 µm. This paper presents an experimental program conducted to evaluate the bond performance in normal-weight concrete of epoxy-coated bars with coating thickness up to 460 µm. Two different bar sizes were investigated, No. 16 and No. 29 bars. Single splices as well as splices of bundled bars were evaluated in the experimental program. The results of the study were implemented in the form of design recommendations for bond of epoxy-coated bars with thicker coatings. The goal is to enhance the future sustainability of concrete bridges by improving the performance of epoxy-coated bars as a corrosion protection system. |
