Abstract
A series of full-scale and in-situ freezing tests were performed to establish a reasonable frost heave prevention method for the national expressways in Japan. These test results showed that the quantity of frost heave is influenced not strongly only by the ground water table, but also by the initial water content of freezing soils. In this study, a simple expression which may predict the frost heave rate at the expressway embankments was derived. The observations in the cold district for three years since 1990 indicated that the expression proposed can explain well the performance of the in-situ frost heaving.
