Life cycle cost analysis on anti-corrosion coatings for steel bridges in Japan

Abstract

A series of surveys on the cost and durability of anti-corrosion coatings for steel bridges used in Japan was performed.  The life cycle cost of anti-corrosion coatings for steel bridges during their design service periods was examined under different corrosion environments.  The combinations of heavy-duty paint coating system as initial coating and the same coating system as repair coating showed the lowest cost when the short interval applied for the repair work. The metal coatings might be reasonable under severe corrosion environments due to their high durability.
