METHOD FOR PRODUCING POLYMERASPHALT CONCRETE MIXTURE Russian patent published in 2021 - IPC C04B26/26 C08L95/00 

FIELD: road and airfield construction.

SUBSTANCE: invention relates to road and airfield construction, namely to a technology for producing polymer-asphalt-concrete mixtures based on petroleum organic binders, and can be used in the construction, repair and operation of road surfaces in all road and climatic zones. Method for producing a polymer asphalt concrete mixture includes heating a mineral material, activating a mineral material with bitumen or deasphalting asphalt or visbreaking residue at the first stage and introducing a polymer-bitumen binder at the second stage, with the following ratio of components, wt. %: road bitumen or deasphalting asphalt or visbreaking residue - 3.0-4.0; polymer-bitumen binder - 2.0-3.0; mineral materials - the rest.

EFFECT: invention increases the adhesion properties of the organic binder with the mineral part of the polymer asphalt concrete mixture, increasing the water resistance, crack resistance of the polymer asphalt concrete, reducing the cost.
