Servo-Pneumatic Universal Testing


Meets ASTM, AASHTO, NCHRP and other testing standards


User friendly, intuitive and reliable Windows® software developed using LabVIEW


Sophisticated data acquisition and control system


Accessories available to perform a range of standard & non standard test methods

For asphalt & unbound materials

This machine is a development of the NAT which was developed by Keith Cooper and Professor Steven Brown at the University of Nottingham. The use of a high precision servo-pneumatic valve in conjunction with a low-friction actuator and sophisticated data acquisition and control, results in a performance that is equal to many servo-hydraulic systems.

Accurate, digitally generated waveforms are applied by the actuator producing repeatable stress variations in test specimens that are simulative of those in a road pavement due to moving traffic. The actuator is double-acting allowing both compressive and tensile forces to be applied. A triaxial cell system is available for the measurement of the resilient modulus of unbound materials.

  • Low cost dynamic loading universal test system ideally suited to testing asphalt and unbound granular materials
  • Double acting low friction actuator with integral stroke transducer
  • Utilizes high performance ceramic spool servo-valve
  • High quality stainless steel frame
  • Accessories available to perform a range of standard and non standard test methods
