Abstract
A design and technological solution to modify the soil temperature regime and maintain the upper boundary of permafrost in the roadbed at the required depth was developed. The main causes of road failure in permafrost regions were identified. The effect of water accumulated at the base of the roadbed on the temporal variation of the inclined permafrost table depending on the road slope was studied using numerical modeling. Numerical modeling was used to select the key geometric parameters of the design and technological solution controlling the temperature variation of the foundation soils. Regression equations describing the temporal variation of the slope of permafrost table in the roadbed were obtained using the mathematical planning of the experiment.
