Servo Hydraulic Universal Testing Machine combining state of the art technology with proven reliability and precision for research and standard testing

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 motorised, adjustable cross head reduces the time between test set-ups. 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.
