  • At present, the subgrade soil of highway in seasonal frost region is not classified with frost heave in accordance with the soil classification standards. This paper presents the test results from a series of closed simulated frost heave tests with sand soil of different clay contents under different water contents, degree of saturations and compactness. Using statistics, the changes of frost heaving ratio of sand soil with different clay contents under different water contents are examined. The classification of frost heave on sand soil with the current standard is performed. The results are of reference value to survey, design, construct and maintain highway, and to provide the reliable materials for the establishment of the designing specification of highways in seasonal frost regions.
