FIELD: transportation.
SUBSTANCE: present invention describes a new type of railway sleeper composed of fibre-stabilised stoneware. By using a plurality of fibre-layered stone plates which are bonded to one another in such a way that prestress is generated in the stoneware, a permanently high-performance-capable sleeper, which is made of natural materials such as granite or basalt which occur almost everywhere on the earth in unlimited quantities and have a substantially longer service life and are substantially more resistant to influences of the weather and the environment than previous solutions, is obtained. Material can be manufactured with substantially less deployment of energy than current systems.
EFFECT: reduced CO2 emissions.
