COMPOSITION FOR ARRANGEMENT OF ROAD PAVEMENTS BASES AND OTHER ENGINEERING CONSTRUCTIONS Russian patent published in 2020 - IPC E01C3/04 E01C21/00 C04B28/04 

FIELD: construction.

SUBSTANCE: invention relates to construction, as well as utilization of large-tonnage wastes of hydrolysis production, and can be used for arrangement of base layers of road pavements and other engineering structures. Composition for arrangement of bases layers of road clothes and other engineering structures contains sand from crushing screenings of 0–5 mm fraction; mineral binder - portland cement with mineral additives; hydrolysed lignin; polymer composite in form of a colloidal solution of high-molecular weight surfactants: poly(2-propenamide) and products of hydrolysis of polyvinyl acetate in the following ratio of components, wt. %: sand from crushing screenings - 82–85; hydrolysed lignin - 5–2; portland cement - 8–6; polymer composite 0.4–0.8 (over 100 %); water - 5–7.

EFFECT: technical result is higher strength of road-building material, containing hydrolysis production wastes, which will expand raw material base for road construction and solve acute environmental problems.
