This study performed accelerated exposure tests on five types of painting systems, which are the most common painting systems for steel bridges in Japan, and discussed corrosion degradation from initial defects on the paintings. Structural steel plates were surface-treated and painted conforming to the Japanese Painting Manual, and circular defects of 0.2 mm, 1.0 mm, and 2.0 mm diameters reaching the steel substrate were created. The painted steels were exposed into an environmental test chamber controlled by the S6-cycle test condition (Japanese Industrial Standards (JIS) K5600) for up to 600 days. Corrosion degradation of the each painting was evaluated based on rusting area from the circular defects, which was measured by using Laser Focus Measuring Instrument at 250 µm intervals. The proposed degradation curves were applied to remaining lifetime evaluation for the painted steels with initial defects to the future conditions.
