ABSTRACT
As a material of embankment of road or railway, Foam Composite Lightweight soil is used. Foam Composite Lightweight soil (abbr. FCL) is mixed foam and cement-slurry that is beforehand mixed with clayey soil or sand. The characteristics of FCL vary depending on the level of cementation and percentage of foam in the FCL. Therefore, the strength characteristic has not been sufficiently clarified. The purpose of this study is to confirm the stability of embankment made of FCL. We carried out the measurements in actual embankments, and the measurements were compared with the calculations based on the past studies. The stability of embankments using FCL was confirmed.
