FIELD: railway construction.
SUBSTANCE: group of inventions relates to the railway track superstructure, namely to a under sleeper pad, a pad manufacturing method and a sleeper comprising such a pad. Under sleeper pad contains two layers, at that the first layer is in/on the second layer. First layer comprises shaped elements provided with recesses. Second layer is made from resilient polymer material. During the pad manufacturing, the first and second layers are combined and connected. In production of sleepers pad is fixed on its bottom, wherein connection is due to penetration and adhesion of liquid concrete into depressions of first layer of pad.
EFFECT: simplified design of under sleeper pad.
