In order to investigate the mechanism of frost heaving in cohesive soil stratum, two types of laboratory tests were performed on cohesive soils. The main concluding remarks derived from these studies are as follows; i) Having high water content and with high saturation, specimens tend to display great amount of moisture migration and large frost heave, especially for small freezing rate. ii) Frost heaving process consists of primary and secondary processes. Furthermore, a simple calculation method of frost heave in laboratory test was proposed. iii) Although the soil sample was in the same state, a different pattern of frost heaving pressure was produced with a variation of void distribution in the specimen. This characteristic is closely connected with occurrence of ice lens.
