REINFORCED SOIL FOR THE CONSTRUCTING THE BASES OF RIGID PAVEMENTS OF ROADS AND RAILWAYS Russian patent published in 2022 - IPC E01C3/04 E02D3/12 C04B28/04 C04B111/20 

FIELD: construction industry.

SUBSTANCE: invention relates to road construction and can be used to strengthen clay soils in the construction of the foundations of top dressings of roads and railways. Reinforced soil for the construction of the foundations of top dressings of highways and railways contains, wt. %: technogenic soil - overburden rocks with at least 16% content of clay particles 60-70, mechanically activated fly ash of dry capture 10-20, mineral binder - fast-hardening Portland cement with mineral additives, strength class 32.5, 6-8, water 12-14, polymer composite in the form of colloidal solution of high molecular weight surfactants: poly(1-carbamoyl ethylene) and polyvinyl acetate hydrolysis products 0.5-0.8 over 100%.

EFFECT: increase in the compressive and tensile strength during bending of road construction material, a reduction in the anthropogenic impact of waste: overburden and heat energy waste on natural ecosystems.
