FIELD: fixed constructions.
SUBSTANCE: road embankment over permanently frozen soils comprises embankment body with a subgrade, interior and exterior earth prisms that are adjacent to both sides of said embankment body, synthetic heat insulation material laid over earth fill slopes and crowns, and slope protection. The heat insulation material is disposed all along the fill slopes, earth prism crowns and slopes and is fastened to them with membranes. The fill slope ratio is 1:1.5 and steeper, whereby the thickness of a heat insulation material to be used is determined.
EFFECT: enhancement of the reliability of roadbed protection against deterioration on permanent frozen soils; providing the capability of carrying out earthwork operations around the clock and reducing their volume.
