METHOD OF REINFORCING RAILWAY TRACK BALLAST SECTION Russian patent published in 2016 - IPC E01B27/02 

FIELD: transport; construction.

SUBSTANCE: invention relates to construction of railways and may be used to track operations associated with reinforcement of ballast section. For reinforcement of track ballast section is formed and impregnated with top ballast layer of liquid polymer binder with formation of carcass structure. In upper ballast layer of ballast section in area of shoulder, slope or inter-track section at a distance from edge of track panel there is a grooved opening. At bottom liquid is fed generate polymeric binder capable of foaming. Restore profile ballast prior to foaming of polymer binder. Forming within ballast layer framework structure in form of an extended stiffener ballast due to formation of composite rubble-polymer binder. Treated ballast portion is maintained at a positive temperature in absence of operating loads for 1-4 hours.

EFFECT: increased retention capacity of main mass of ballast layer to prevent caving of ballast materials on track sections in curves and in process slopes of inter-track zone.
