• Basic idea and empirical ground for the standard criteria, now in use in Hokkaido, as to the depth of pavement structure including base and subbase of select materials are stated.Some troublesome phenomena, such as warping and cracking of pavement, and growth in residual subgrade of ice masses have been observed in frigid districts. Some detailed studies, based on the theory of heat conduction, of frost aspects of residual subgrade and resultant depth of frost penetration after replacement or cover with coarse grained select material are given.Conception for determining the proper depth of pavement structure or of select fill and a suggestion for making use of material of high moisture content as reducing agent for frost penetration are presented.
