METHOD OF CONSTRUCTING ROAD EMBANKMENT Russian patent published in 2017 - IPC E02D17/18 

FIELD: construction.

SUBSTANCE: method of constructing road embankment includes delivering a loose material to the construction site, forming in layers a road embankment of the loose material packaged in portions within the layer in watertight cells of a durable material, forming a continuous tape of a specified length. As the cells, worn tires are used, which are fastened together with horizontal chords of a synthetic cable, in the directions both along the road axis and across it. The tires of each underlying cell layer are fastened with vertical cords of a synthetic cable with the tires of an overlying layer. The first continuous tape is laid on the substrate from the water-permeable geotextile layer, after which its cells and the intervals between them are tightly filled with the loose material, previously having fixed the vertical cords on them. The second continuous tape is laid on the surface of the compacted layer formed, so that the tires in every longitudinal row rest on two tires of the underlying row, and the tires forming the second continuous tape are fastened by vertical cords with the tires of the underlying layer. The cells of the second continuous tape and the intervals between them are tightly filled with the loose material, previously having fixed them the vertical cords for fastening with the tires of the overlying layer. The upper continuous tape of the road embankment is tightly filled with the loose material without fixing the vertical cords on its upper side, wherein the side walls of the road embankment are formed as slopes with an inclination angle smaller than the angle of the natural slope of the loose material, the width of the continuous tapes decreasing bottom-top.

EFFECT: ensuring the embankment reliability and durability in the North conditions, its water permeability for flood waters, improving the technical and operational characteristics of the embankment.
