Abstract: In order to study the change rule of modulus of resilience of lime improving silty clay under the action of freeze-thaw cycle,bearing plate method is used to determine the soil modulus of resilience,explore different freezing and thawing times,mixing cement dosage,moisture content and compaction how affect lime improved soil modulus of resilience. Lime improved soil under different freezing and thawing times for micro electron microscope scanning（ SEM）,analyzed from the microscopic view,and some important conclusions are obitained.
Keywords：
