Analysis of carrying capacity of concrete sleepers for switches and crossings under static and dynamic load

The testing of bearing capacity under static and fatigue loading is mandatory in case of prestressed concrete sleepers for switches and crossings. The authors present the static testing required according to EN13230-4:2009, and the optional dynamic testing of sleepers for switches and crossings, which is conducted at the customer's request only. The criterion for positive evaluation in accordance with the standard is met based on static test results. The determinants from EN13230-2: 2009, with deviations in the number of load cycles, are applied during dynamic testing.
