GEOCOMPOSITES BASED ON MAN-MADE SOILS OF ANTHROPOGENIC GENESIS AND METHOD FOR THEIR PRODUCTION Russian patent published in 2021 - IPC E02D3/12 E01C3/04 E01C21/00 C04B28/04 

FIELD: construction industry.

SUBSTANCE: group of inventions relates to geocomposites used as bases, additional layers of bases and lower layers of coatings of highways and airfields, backfill soil during planning works, the construction of slopes and earthworks, for the construction of waterproofing structural layers, as well as geochemical barriers, as a backfill material in geoecological works aimed at the reclamation of disturbed areas. The geocomposite contains a mixture of technogenic soils, particularly those technologically displaced and technologically transformed, and anthropogenic coarse-dispersed soils formed as a result of construction activities, such as concrete, bricks, silicon dioxide: sand; polyethylene; wood: cellulose; textiles; gypsum; polyvinyl chloride; synthetic rubber: rubber; paper, cardboard; glass; ferrous scrap: iron in an amount from 0 to 70% of the volume of the mixture of technogenic soils, the complexing additive “PolyGeo” in an amount from 3 to 20% of the mass of the mixture of technogenic soils, while the mixture of technogenic soils has a pH greater than or equal to 3.0, contains clay particles less than 0.002 mm in size: at least 10% of the mass of the mixture of technogenic soils, has a fractional composition in the range of 0-50 mm, has a humidity in the range of 0 to 70% and contains no more than 45% of organic substances from the mass of the final mixture . The group of inventions is developed in the primary claims and subclaims of the formula.

EFFECT: production of a geocomposite of increased density, connectivity of soil particles and reduced porosity while simultaneously achieving neutralization and disinfection of the initial components.
