Servo-Hydraulic Universal Testing Machine


description : The Servo-Hydraulic Universal Testing Machine (CRT-UTM-HYD) is a well designed, inexpensive machine specifically developed for the testing of materials used in pavement construction. A motorized, adjustable crosshead reduces the time between test setups. The programmable temperature cabinet provides the possibility to perform frequency/temperature sweeps. Accurate waveforms are digitally generated and applied by the actuator producing repeatable conditions that are simulative of those created by moving or static vehicles. The actuator is double-acting allowing both compressive and tensile forces to be applied. Various systems are available for the measurement of the modulus of unbound materials.

features :
  • Designed to perform a range of tests on asphaltic paving materials, sub-grade soils and granular sub-base materials
  • Double acting fatigue rated hydraulic actuator with integral stroke transducer
  • Utilises Star servo valve with ‘Sapphire Technology’
  • Motorised adjustable lower crosshead with automatic hydraulic frame clamping
  • Integral programmable temperature controlled cabinet
  • Issued with UKAS accredited certificate of calibration for EN 12697-24; EN12697-25, EN 12697-26
  • Accessories available to perform a range of standard and non standard test methods
  • Can be supplied with standard software to perform EN, ASTM andAASHTO test methods and universal software with which to design non standard test routines


Key Uses


  • Assessment of resistance to permanent deformation (rutting)
  • Measurement of stiffness modulus
  • Assessment of resistance to fatigue cracking
  • Resilient modulus of unbound materials
  • Mix design
