内容記述 | As a fundamental investigation for the maintenance of forest road surface in winter, we measured frost-heaving of forest road. We set 8 measure points and measured the frost-heaving height of each point at intervals of about 10 days from early in December to early in April. As a result, it appears follows. 1. there is nearly connection between frost-heaving and solar rediation. Frost-heaving is higher at hide place than at sunny place and also the period of frost-heaving is longer at hide place than at sunny place. 2. In each position of road, the frost-heaving is lowest at shoulder and lower at the cutting side then at banking side. 3. It is no effection of ballast less than 10cm depth to decrease og frost-heaving. 4. There is an inverse relation between frost-heaving and temperature. At hide place the frost-heaving reachs highest level at late in February and finishs at late in March, but at sunny place 15~20 days earlier than hide place. 5. Ae rain in March accelerates the thaw. | |||||||||
