FIELD: construction.
SUBSTANCE: invention relates to construction, namely to road structures, and can be used at erection of road bed field of motor roads and roads with low traffic on weak soils, including flooded swamps of 2nd and 3rd types. Design of road bed for construction of roads and industrial roads with low traffic on weak soils, including flooded swamps of 2nd and 3rd types includes local substandard hydromorphic soil, geo-synthetic nonwoven water permeable web. Made with layers of geotextile, which are formed in two cage structures with bulk protective upper layer. Layer for first bearing cage is whole by width fabric from geotextile, fastened and laid on width of base of fill with allowance by width of top and slope part of support frame, on which layer of local substandard soil is backfilled layer-by-layer by thickness of bearing cage. Then, edges of first bearing cage geotextile are sealed with overlap, over first cage, second cage is similarly arranged, on surface of which protective layer of fill is backfilled from filtering soils.
EFFECT: technical result consists in reduction of non-uniformity of base fill sediment, ensuring redistribution of sediments in cross section of fill with its decrease along axis, meeting during construction and operation of all technical requirements for strength and stability for each erected structural element of cage.
