This paper focuses on material properties of more than 400 soils recovered from disaster debris in Iwate Prefecture generated by the 2011 Great East Japan earthquake and tsunami. Analyses in this study verified that recovered materials basically have sufficient quality as geomaterial from the viewpoint of chemical and physical properties, being expected to be utilized in geotechnical applications though additional processes such as mixing of steel slag and crushed concrete affect material properties. Some results raised an experimental concern regarding applicability of existing test standards for assessment of recovered materials.
