FIBER-CEMENT -SOIL MIXTURE Russian patent published in 2022 - IPC E02D3/12 E01C3/04 E01C7/36 C04B28/04 C04B111/20 

FIELD: road construction.

SUBSTANCE: The invention is related to the road construction and can be used to strengthen soil when installing layers of foundations and road pavements. Fiber-cement-soil mixture contains, by weight%: natural soil 63.0-80.0, Portland cement 4.0-10.0, basalt fiber, which is a waste product of basalt thermal insulation boards, length from 0.01 to 3.00 mm, or glass fiber with length from 10.00 to 30.00 mm, or polypropylene fiber with length from 10.00 to 30.00 mm, or carbon fiber with length from 10.00 to 30.00 mm, 0.5-3.5, water - the rest. The invention is developed according to dependent claims.

EFFECT: The present invention increases the tensile strength during compression, bending and splitting under the condition of high crack resistance of reinforced soils, increases frost resistance and decreases water saturation.
