METHOD FOR INCREASING ROAD PAVEMENT SURFACE WEAR RESISTANCE Russian patent published in 2020 - IPC E01C7/35 E01C19/43 

Abstract RU 2719840 C1

FIELD: construction.

SUBSTANCE: invention relates to the field of road construction, namely to methods for increasing wear resistance of the roadway surface layer, and can be used in construction and repair of motor roads. Method for increasing wear resistance of surface layer of roadbed includes mechanical action on road surface. Mechanical action is performed by rolling of regular relief on surface of roadbed with projecting parts and grooves, then slots are filled with binding substances to depth of not less than 1/3–2/3 of slot depth, wherein pattern of regular relief is made so that water flow from road surface is provided.

EFFECT: increasing wear resistance of surface layer of roadway with simultaneous improvement of aesthetic and functional properties.
