Static, fatigue and dynamic tests of concrete sleepers

Concrete is a widely used construction material, requiring fatigue failure testing. We perform static, fatigue and dynamic tests of concrete sleepers and other construction components.

What is tested

  • Standard and switch concrete sleepers according to ČSN EN 13 230


Test bench basic parameters

  • Uniaxial hydraulic “pulsator” with the power range of ±2500 kN and the piston rod working stroke of ±250 mm
  • PC microscope for measuring cracks during the test with a resolution of 0,005 mm


Options and advantages

  • Frequency of loading during fatigue and dynamic tests of up to 6 Hz
  • Accurate monitoring of crack development and its computer display with accurate measurement
  • Fatigue tests can be performed 24 hours a day with monitoring of safety limits
  • It is possible to test and measure the electrical resistance of the sleeper during rain simulation


Reference projects

  • ŽPSV: Concrete sleepers of type B91T a BC12
  • On Rail Group: Tests of concrete sleepers B70 a B90
