摘要
泡沫塑料作为一种新型道路隔温材料 ,用来替代传统的防冻层 ,以保障路基不产生冻结、聚流和层状冰晶体的析出 ,并起到预防道路冻胀和翻浆的作用。文章介绍了俄罗斯在道路建设中应用泡沫塑料 Styrofoam HI- 5 0铺设隔温层的经验 ,为在季冻区筑路及其防治公路冻害提供一种理论和实践依据。
Foamed plastic, a new road insulating material, can be used for replacing the traditional frost protection courses, to prevent freezing, migrating of moisture and layered crystal separating out, and prevent subgrade form frost heave and frost boiling. This article describes the application of foamed plastics, Styrofoam HI-50, for road insulating layer in the construction of road in Russia, and it provide a reference experience for building a road and controlling the frost damage in the seasonal frost region.;
