METHOD OF CONSTRUCTING RAILROAD TRACK AND TRACK DESIGN Russian patent published in 2009 - IPC E01B2/00 

FIELD: railway transport.

SUBSTANCE: invention relates to railway transport, particularly to railroad track construction methods and track designs with track bed providing for elastic interaction with rolling stock. Proposed method of constructing railroad track comprises constructing contact surface of earth or peat foundation with ballast layer and that of the latter with convex semi-cylindrical sleepers of designed radius. Prior to ballast layer soil filling, the foundation is graded along circular arc. The said ballast layer is graded and compacted to make, on its surface crosswise section, arc-like lengthwise concave recesses that mate sleeper arc-like bulges. Railroad track structure comprises earth or peat foundation graded along circular arc and ballast layer with surface arc-like concave recesses mating arc-like sleeper bulges arranged along circular arc.

EFFECT: safe and reliable operation of foundation and ballast layer of railroad tract upper structure.
