| Outline of Final Research Achievements |
We sought to develop the evaluation method of adhesion amounts of airborne sea salt for the maintenance of coastal structures including bridges. We discussed acquisition methods of meteorological data and airborne sea salt concentrations, washing-out and penetration into the inside of concrete members of deposited salt. We also introduced a statistical method for evaluating adhesion amounts of salt. In addition, we developed aerodynamic countermeasures to mitigate the adhesion of airborne sea salt particles on bridge girders. Moreover, the evaluation of the performance of an old bearing was conducted. Effects of de-icing salt as well as sea salt were also investigated.
