METHOD FOR TREATING ROAD COVERING Russian patent published in 2018 - IPC E01C7/35 C08L95/00 

FIELD: construction.

SUBSTANCE: invention relates to the construction and repair of highways and can be used for the treatment of road asphalt concrete and concrete coverings with the use of compositions – film formers based on a polymer binder. Method for treating a road surface by applying a polymer composition with a filler, followed by its curing, is that treatment is carried out with the polymer composition comprising a hydrocarbon solution of an acrylic polymer based on a n-butyl methacrylate copolymer with methyl methacrylate in an amount of 60–75 % by weight, dispersed anti-ice coating "Grikol" in an amount of 10–20 % by weight, and as a filler it contains structure-forming polymeric and mineral dispersions of the fraction 0–3.5 mm in an amount of 15–20 % by weight, herewith the application of the polymer composition to the covering to be treated is carried out at a flow rate of 0.10–0.60 kg/m², outdoor temperature from -5 °C to +40 °C, followed by curing for 30–120 minutes, and the hydrocarbon solution of the acrylic polymer based on the n-butyl methacrylate copolymer with methyl methacrylate contains a mixture of hydrocarbon solvents in an amount of 70–80 % by weight, mixture of co-solvents in an amount of 5–10 % by weight, and the acrylic polymer in an amount of 10–20 % by weight.

EFFECT: increase water resistance of the treated covering, frost and corrosion resistance, wear resistance, improvement of transport-operational characteristics, providing safety and comfort of movement, prevention of slipperiness at zero and negative dangerous icy condition temperatures, manufacturability and availability for wide application.
