 note = {This paper is concerned with the change in soil structure on specimens subjected to freezing and thawing. The samples used for the experiments were undisturbed volcanic ash cohesive soils collected from below the frost depth at Karuizawa Plateau, Nagano Prefecture, where various types of frost damage have occurred. Results obtained indicate significant change in soil structure as evidenced by the scanning electron micrographs taken on soil samples after freeze-thaw cycles.},
