Silty clay modified by fly ash and crumb rubber is a kind of sustainable subgrade filler which has good anti-freeze-thaw resistance stability but wake vibration isolation performance. The objective this study was to improve the soil investigate effect composite structure XPS plates indoor impact test. First, performance silty clay, respectively evaluated. Second, plate’s thickness intensity on were Third, test groups under condition freeze-thaw cycles assessed. results show that can be effectively improved setting plates. certain effect, especially in vertical direction. Considering costs, 5cm optimum thickness. great cycles, so it suitable applied road seasonal frozen regions.
