The Servo-Hydraulic Universal Testing Machine is a well designed, inexpensive machine specifically developed for the testing of materials used in pavement construction. A motorized, 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.
- Designed to perform a range of tests on asphaltic paving materials, sub-grade soils and granular sub-base materials

控制系统及软件
This machine can be controlled using our Standard Acquisition and Control System along with Universal Software™. Universal Software™ is user friendly, intuitive and reliable Windows® software developed using LabVIEW™. Universal test software for the development of test methods using static, sinusoidal, haversine, square, triangular with user selected frequencies and data collection rates. Stored test data can be imported into a spreadsheet package to be analysed by the user. Utilities are included for transducer check, diagnostic routines and calibration.
Alternatively, 我们的下一代, digital data acquisition and control unit cDAC™ Advanced Data Acquisition System brought together in alliance with our flagship software DIMENSION™ gives you the power to perform the most demanding of tests with your materials testing equipment.
cDAC™, our next generation class leading digital controller is unparalleled in its field and suitable for advanced testing required for research.
