摘　　要：针对北方寒冷地区道路冻胀翻浆与地基融沉等病害,开展了轻质土在道路基层中的应用研究,并在试验路铺筑的实践基础上,阐述了气泡混合轻质土的力学特性与试验结果分析。初步证明,轻质土在冻土地基的隔热保温与台背填土的防冻胀方面效果比较明显。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.
