 note = {In cold regions, frost heave action causes serious damage on road pavements and its facilities such as manhole. At the construction sites of Tateshina plateau in Nagano prefecture, it was necessary to utilize frost-susceptible volcanic cohesive soils for subgrade and subbase course. Field tests of countermeasures against frost heave and prevention methods of adfreezing force of soil using manhole have been conducted to examine the frost resistances of several kinds of untreated subgrades and those treated with stabilizing materials. Also, we have been measured the distribution of temperature and heat flow in the ground. This paper describes the results of these tests.},
