Corrosive environment survey, rust survey and exposure test using attachable small test pieces were investigated. Rust evaluation of weathering steel bridges were carried out. In exposure test, amount of long-term corrosion loss that was estimated by exposure test using attachable small test pieces of one year and multi-year were compared.
