Zusammenfassung:To provide a production method of biodegradable construction material with improved strength, biodegradable plastic mixed soil, and a ground solidification method.SOLUTION: A ground solidification method comprises the steps of: producing biodegradable plastic mixed soil obtained by mixing soil to be mixed and biodegradable plastic P with grain size distribution corresponding to grain size of the soil to be mixed (S3); heating the biodegradable plastic mixed soil for predetermined time at temperature equal to or more than a melting temperature of the biodegradable plastic (S4); and cooling the biodegradable plastic mixed soil to temperature equal or less than a glass transition point of the biodegradable plastic P to solidify it (S6).SELECTED DRAWING: Figure 2 【課題】より強度を向上させた生物分解性の建設資材製造方法、生分解プラスチック混合土、および、地盤固化方法を提供する。【解決手段】混合対象土と、当該混合対象土の粒径に対応した粒度分布を有する生分解プラスチックPと、を混合した生分解プラスチック混合土を生成し(S3)、生分解プラスチックが融解する温度以上、前記生分解プラスチック混合土を所定時間加熱し(S4)、加熱した生分解プラスチック混合土を、生分解プラスチックPのガラス転移点以下まで冷却して固化する(S6)。【選択図】図2
