Servo-Hydraulic Universal Testing Machine 25kN

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.

Key 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
• Star servo valve with ‘Sapphire Technology’
• Motorized adjustable lower cross head with automatic hydraulic frame clamping
• integral programmable temperature controlled cabinet
• Issued with UKAS accredited certificate of calibration for EN 12697-24; EN 12697-25, EN 12697-26
• Accessories available to perform a range of standard and non standard test methods

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

Control System and Software
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, our next-generation, 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.
