Was carried out on the basis of DIN EN 13230-2 (concrete sleepers).
A load of 150 kN was selected for the fatigue test. This corresponds to an axle load of 250 kN and a train speed v < 200 km/h.
A static load of 1.2 x 150 kN = 180 kN was applied before the fatigue test.
After the fatigue test the static load was increased to 2 x 150 kN = 300 kN.
Using grooved plate Rph 1 with the dimensions 160 mm x 345 mm the fatigue test was carried out under the rail support on two sleepers (height 120 mm).
A 5 mm thick intermediate plate of synthetic material was also installed under the grooved plate.
The first sleeper was subjected to 5 million load cycles and the second to 2 million load cycles.
