抄録
In road construction、 surplus soil from around the site is put to use in the interests of environmental protection and for other reasons. Such soil that is soft and cannot be used for construction in its untreated state is called unsuitable soil、 and requires a certain amount of processing before it can be used in construction. A road-building project using reinforced earth walls was planned in Hokkaido、 but the surplus soil produced around the site was found to be unsuitable. To address the issue、 improvement using a solidifier was considered. Solidified soil is a cohesive material with no angle of internal friction、 but reinforced earth walls have a structure that requires friction between the soil and the reinforcing material、 necessitating the use of a substance with an angle of internal friction for the embankment. An earth wall embankment was therefore constructed by improving the soil to form crushed、 solidified material with an angle of internal friction.
