资源简介：
The invention relates to a method which enables sleepers to be produced for the railway track superstructure having optimised performance characteristics， in a reliable and cost-effective manner. The method according to the invention provides the following production steps: a) providing a mixture 10-60 % mass of which consists of a granulate of a plastic， which is deformable by applying heat， and the remainder of which consists of a sand having a bulk density of 1.4-2.0 g/cm 3; b) heating the mixture to a temperature of 150-200° C.; c) pouring the mixture into a press mould reproducing the sleeper; d) pressing the mixture in the mould at a pressing pressure measured in the mixture of 1-5 MPa over a pressing period of up to 60 minutes; and e) removing the sleeper from the mould.
