“…In Japan, social infrastructure is becoming more than 50 years old since its construction [7]. Moreover, currently used bridge coatings are considered to have a life expectancy of at most 30 years, even for heavy-duty corrosion resistant coating systems [8]. Therefore, among social infrastructures, the maintenance of coated steel structures is aimed to regain the necessary slip coefficient by recoating.…”

With the development of paints, high‐friction organic zinc‐rich paints with slip coefficients more than 0.45 have been advanced, making it possible to obtain more sophisticated and higher quality high strength bolted friction joints. Moreover, comparing to the inorganic zinc‐rich paints used at present, organic zinc‐rich paints are more appropriate for using in situ construction. However, since the application conditions of organic coatings have not been specified, it is recommended that a slip test should be carried out separately for each surface preparation to confirm the slip coefficient. In this study, slip tests were carried out on high strength bolted friction joint specimens to investigate the influence of high‐friction organic zinc rich paint film thickness and surface preparation on the slip coefficient. Furthermore, based on the experimental results, a surface preparation that can consistently produce a high slip coefficient is proposed.

“…The authors have performed laboratory cyclic accelerated exposure tests on steel bridge components, such as bare structural and weathering steel plates, welded joints, painted and metallic coated steel plates, etc. [9][10][11][12][13][14][15] In these studies, the fundamental corrosion behaviours were presented from the accelerated exposure test results. Comparing the accelerated test data with the field data, the correlation between the two tests was also presented.…”

The present study performed accelerated exposure tests on 5 types of painting systems, which are commonly used for steel bridges in Japan, and discussed corrosion degradation from initial defects on the paintings. The structural steel plates were surface treated and painted conforming to the 'Japanese painting manual', and circular defects with 0?2, 1?0 and 2?0 mm in diameters reaching the steel substrate were created on each of the painted plate. The painted steels were exposed into an environmental testing chamber controlled by the S6 cycle test condition, which is a laboratory cyclic accelerated exposure test condition of spraying/wetting/drying, for up to 600 days. The corrosion degradation curve of the each painting system was evaluated based on rusting area from the circular defects, which was measured by using laser focus measuring instrument at 250 mm intervals. The proposed degradation curves were applied to evaluating remaining lifetime of the painted steels with initial defects to the future conditions. The evaluation procedure for field environments was also presented based on the acceleration coefficient of the S6 cycle tests and the amount of flying salt.
