FIELD: construction.
SUBSTANCE: invention relates to construction and can be used in construction, reconstruction and repair of motor roads on weak heaving soils. Road structure on weak base for motor roads includes upper working layer of fill and fill body equipped with reinforcing elements. Upper working layer of fill is made with thickness of 1.1…1.2 m, and body of fill is made from alternating layers of bulk non-heaving soil and webs of metal system, at edges connected with volumetric framed structures of box type, filled with rock soil with stone size of not less than 70 mm.
EFFECT: technical result consists in improvement of resistance and stability of earthwork structure on weak base at seasonal deformation under unequal action of forces of frost heaving and precipitation during thawing, high strength, rigidity and stability of structure.
