| Abstract: | In view of the distresses including such as frothing due to frost heave and the settlement of ground base, the frost thawing settlement, an applied study was made on the application of light-weight soil with air-bubble to the base course. Based on the Practice of a trial road section, this article describes the mechanical properties of this soil, with analysis on trial result. It has been proven that this soil can bring about better results in the thermal insulation for frozen ground base and frozen heaving resistance at the backfill of abutments on the frost ground. |
