Abstract : The authors make the following conclusions: The stability of road structures in the permafrost zone depends on the carrying capacity of the base soils which is determined by the degree of their settlement. Settlement of soils depends on the type of moistness (ice content) of the soil. The schematic charts for the settlement of base soils provides a basis for selecting a principle for planning the road structures, specifying the height of fill and choosing the preliminary calculation of the scales of earth-moving operations. Selection of the method for estimating the final settling depends on the extent of moistness in the base soils, the presence or absence of mossy-vegetative interstratification, time of performing the work, and type of soils in the base.
