Performance properties are of central importance for the design of road structures. The institute has 4 servo-hydraulic testing machines for performance response. A further testing machine with a spindle drive is available for the analysis of the low temperature behaviour.

Application

  • Performance speech
    • Deformation properties
    • Fatigue properties
    • Low-temperature behaviour
  • Dynamic compression and tensile tests under defined temperature conditions
  • Stamp penetration tests
  • Splitting tensile tests
  • Bending tensile tests
  • Testing of the layer bond (dynamic and quasistatic)
