Mechanical Characteristics of Incineration Bottom Ash from Disaster Waste Caused by the Great East Japan Earthquake

The Great East Japan Earthquake resulted in extensive damage and left a vast amount of debris. The debris from the disaster has been incinerated to reduce the volume. This study focused on the predicted future demand of land soil, for example, to use in post-disaster reconstruction works. In order to examine the availability to recycle and utilize the incineration bottom ash from the disaster debris, the material properties of the incineration bottom ash was evaluated by soil experiments. Features of incineration bottom ash recycled material were compared with general incineration bottom ash from F City. A modified CBR test (JIS A 1211) was adapted to evaluate the availability of using the material as subgrade and roadbed material. A constant pressure direct shear test was employed to assess the shear properties. The results show that the incineration bottom ash recycled material has equivalent shear properties with regard to physical composition compared to general incineration bottom ash. The study reports that there is a possibility for incineration bottom ash recycled material to be effectively utilized as a roadbed material and used as a soil material with varied strengths.
