FIELD: transport.
SUBSTANCE: proposed method comprises complete cutting-out of ballast, its cleaning, filling lower layer to be leveled and compacted, filling new layer of breakstone thereon. Compaction of ballast lower layer is carried out by vertical static and dynamic effects brought about by wedge-like compactors on ballast surface in zones between sleepers. Said wedge-like compactors are mounted on breakstone cleaning or special ballast-compacting machine. New layer of breakstone is compacted by hammering machine and dynamic stabiliser that transfers vibration onto assembled rails and sleepers and onto breakstone ballast.
EFFECT: higher stability of track.
