Abstract
In this paper, an approach for asset management of decrepit social infrastructures is proposed. The management system is based on a sequence of inspections. Since Japan is surrounded by sea, coastal revetment is necessary. However, a great number of the coastal facilities were built in the same period of rapid economic growth, and therefore they have aged at the same time. We need to maintain these social infrastructures efficiently in an aging society with a falling birthrate using asset management. It is important to integrate our practical knowledge, develop maintenance skills and produce a road map which indicates how to use this information in the field.
