Zusammenfassung:To provide a method for manufacturing modified soil that can efficiently obtain modified soil with low costs by minimizing the additional amount of a modifier that has solidification action to cement or the like and utilizing the solidification action as much as possible.SOLUTION: The method for manufacturing modified soil in which the strength is improved by adding a modifier that has solidification action to target soil to be modified, comprises: performing, for the target soil, a modification target soil evaluation test for grasping the solidification inhibition capability of solidification inhibition substances that inhibit the solidification action of the modifier; adding a supplemental material that eliminates the solidification inhibition capability to the target soil; and adding the modifier to the target soil to obtain modified soil.SELECTED DRAWING: Figure 2 【課題】セメント等の固化作用を有する改質材の添加量を必要最小限にしながら、その固化作用を最大限活用して、コストを抑えて効率良く改質土を得ることができる改質土の製造方法を提供する。【解決手段】改質対象である対象土に固化作用を有する改質材を添加して、強度が改善された改質土を製造するにあたり、前記対象土について、前記改質材の固化作用を阻害する固化阻害物質による固化阻害能力を把握するための改質対象土評価試験を行った上で、該固化阻害能力を消失させる補助材を対象土に添加すると共に、前記改質材を添加して改質土を得ることを特徴とする改質土の製造方法である。【選択図】図2
