Availability: Find a library where document is available Abstract: The replacement method for the control of frost penetration of soils is commonly used for pavements on roads with light traffic in Japan. However, because of recent concern for the protection of the natural environment and shortages of natural resources, special frost control techniques such as the insulation method now need to be developed. This method prevents frost damage from frost penetraion by the use of insulation boards, placed between the subgrade and subbase in road shoulder areas only. It is intended for pavement construction where narrow existing gravel roads with a sand and gravel subbase are widened. A frost control design method that combines the insulation method used for road shoulders with the replacement method used in the travel lanes is described. Estimations from calculations are compared with observed measurements of frost heave and frost penetration obtained from the test road in winter. From the results of observations on the experimental sites, this new method is found to be promising for the control of frost penetration in both the widening and the paving of existing gravel roads.
