Frost heave is one of the important factors affecting long-term stability and safe operation subgrade in seasonally frozen soil regions. To investigate anti-frost effect foam concrete insulation composite structure subgrade, a multi-physics fields coupling numerical simulation was employed. From perspective hydrothermal process ground temperature distribution, maximum freezing depth, ice frost are systematically analyzed. The results indicate that foamed layer exhibits significant effect. Meanwhile, to alleviate sunny-shady slopes on soils regions, combining XPS board with recommended. Moreover, appropriate measures for proposed, which considering different characteristics. findings can serve as reference prevention control highway application layers seasonal
