Abstract
This study forcus on the liquefied stabilized soil one of the cement treated soil. To begin with, in this study, the mechanical properties of liquefied stabilized soil which incureded surplus soil or surplus soi mixed coal ash were revealed. Next this study conducted to investigate the reuse of excavated liquefied stabilized soil under the assumption that the liquefied stabilized soil was excavated in order to do repair or maintenance. As a results the characteristics of excavated liquefied stabilized soil was depended on cement content. It was revealed that the excavated liquefied stabilized soil can be reused directly, need to some improvement. Futhermore it was revealed that when the excavated liquefied stabilized soil was applied to liquefied stabilization method again, it have equivalent to mechanical properties of the liquefied stabilized soil and satisfy the Japanese geo-environment standard.
