Abstract

This study examined to evaluate corrosion degradation of coatings systems for steel bridges. Three types of painting systems, which are called as A, C, and I painting systems, and four types of metallic coating systems, which are named as Zinc plating, Zinc-Aluminum alloy spraying by two methods and Aluminum spraying, were used in the test. After coating works, scribed circles reaching steel substrate were made in the coated surface of the specimens. The test specimens were corroded in an accelerated corrosion cyclic test condition conforming to JIS K 5621 during 300 or 400 days. From the test results, appearance change and rust propagation from the scribed circles were discussed. Based on the blistered area, degradation curves for the painting systems were also proposed.
