FIELD: process engineering.
SUBSTANCE: invention relates to production of road-metal form reinforced concrete claw sleepers. Rock is heated to fusion point to cast the melt in moulds to get definite-size road-metal.
EFFECT: higher force of sleeper shift in ballast prism ruled out ejection at extreme temperatures and departure from railway track upper structure standards.
