METHOD FOR PRODUCING A SLEEPER FOR USE IN THE RAILWAY TRACK SUPERSTRUCTURE
The invention relates to a method which enables ties for the track superstructure which have optimized performance characteristics to be produced in an operationally reliable and cost-effective manner. To this effect, the method according to the invention provides the following work steps: a) providing a mixture which consists of 10-60% by mass of a granulate of a plastic material deformable by the application of heat and, as the rest, 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) filling the mixture into a compression mold in the shape of the tie; d) compressing the mixture in the mold with a compression pressure of 1-5 MPa measured in the mixture over a compression duration of up to 60 minutes; e) removing the tie from the mold.
