VERFAHREN ZUM HERSTELLEN EINER SCHWELLE FÜR DEN EINSATZ IM GLEISOBERBAU
The invention relates to a method which enables sleepers to be produced for the railway track superstructure, which have optimised performance characteristics, in a cost-effective and reliable manner. The method according to the invention provides the following production steps for this purpose: 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/cm3; 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.
