Abstract

A series of studies aims to develop superabsorbent polymer-based soil conditioner as new soil conditioner in classification sorting treatment of higher water content soil and viscosity soil. In this study, the soil improvement effect by the soil improvement material based on super absorbent polymer, the property of the improved soil was verified. As a result, the following contents were revealed. (1) Improvement effect by superabsorbent polymer-based soil improving material is remarkable for any target soil, and in case of homogeneous soil, improving effect can be expected more in high water content condition. Superabsorbent polymer-based soil conditioner is an improvement based only on moisture absorption of interstitial water. (2) The improved soil changes in dry density and void ratio compared with the soil before improvement, but it can be used for filling if properly managed. (3) Expansion due to water absorption of the improved soil is considered to be minor in the use of the embankment.
