The basic study was performed on the mechanical analysis of frost and heave using program FROST by CRREL, U.S. army corps of engineers. The characteristics of frost heaving in pavement was analyzed by considering climate, pavement sections and subgrade soil conditions in Korea. Water tables were located at the depth of 0.35m, 2m and 3.35m from subgrade. Inputs were evaluated inevitably from the existing references. As a result frost heave and depth were evaluated with respect time. Maximum frost heave decreased lowering the water table and maximum frost depth was less than 15cm from subgrade. Frost action did not affect seriously on the analysis sections.
