It has been reported that inspection methods and measures have not been established for damage to weathering steels, and there are many cases in which the judgment at the site is often lost. Therefore, it is simple and highly effective, and by inspectors It is required to establish an inspection method that does not vary and a clear countermeasure according to the state of rust that has been evaluated. Therefore, Japan Bridge Construction Association proposes a method to easily judge the quality of rust using a rust sample, and a countermeasure that is divided into each case.
