The Servo-Hydraulic Universal Testing Machine (CS-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.
- Designed to perform a range of tests on asphaltic paving materials, sub-grade soils and granular sub-base materials
