Servo-Hydraulic Universal Testing Machine (25kN)

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.

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
• Utilizes Star servo valve with “Sapphire Technology”
• Motorized adjustable lower crosshead with automatic hydraulic frame clamping
• Integral programmable temperature controlled cabinet
• Accessories available to perform a range of standard and non-standard test methods

Software:

• User friendly, intuitive and reliable Windows® software developed using LabVIEW™
• Standard test software available to meet specific EN, ASTM and AASHTO test methods
• 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
