FIELD: construction, particularly to build roads, airports of silt soil, for instance in northern zones having seasoned deeply frozen or permafrost soil, high ground water level, mainly in summer periods.
SUBSTANCE: road structure has pavement with underlying layer, road bed reinforced with binding agent and water-proofing shell. The water-proofing shell has lower part inclined from embankments to road bed axis. Road structure also has gap for water discharge from shell into underlying draining layer located under road bed. Water-proofing shell and draining layer are made of soil reinforced with binding material, for instance with oil. Upper part of strengthened shell is used as paving underlayer.
EFFECT: possibility of object construction of in-situ silt or wet soil, increased strength and stability during road usage.
