Modular Servo Hydraulic Asphalt Tester AST Pro

Main features
  • Brand new technology ihcluding the new revolutionary E-Mech Servo-electromechanical actuator
  • Easy and versatile with his fully integrated modular system, that includes a 19 kN capacity hydraulic labyrinth actuator
  • Enhanced environmental cabinet that grants a wide temperature range with fast and accurate temperature control
  • Easy-to-use and ergonomic testing system
  • Clarity in results with the Integrated Multi Axis Control System (IMACS)
  • Fully integrated and very compact in design, a perfect solution for both static and mobile testing facilities

  • Compact design requiring, in general, a smaller footprint
  • Easy to use
General description
General description
The AST Pro belies the power and versatility if this fully integrated modular system. AST Pro is based on the tried and tested technology of the AMPT Pro and its high performance servo-hydraulic labyrinth bearing actuator.

Now you can perform all the most common asphlt test standards in one high performance, compact, modular, easy-to use machine.

AST Pro allows to perform a wide range of tests, including the ones compatible qith AMPT Pro (permanent deformation, cyclic compression, indirect tensile stiffness, indirect tensile fatigue, crack propagation, direct tension-compression, dynamic/complex modulus) plus triaxial compression, four-point and two-point stiffness and fatigue flexural tests.

IMACS Digital Controller and Data Acquisition System

IPC Global's world leading IMACS digital controller and data acquisition system is at the heart of all our servo-controlled testing systems. It provides excellent waveform fidelity from integrated channel acquisition and control functions, at speeds of up to 5 kHz simultaneously on all channels.
The IMACS utilizes flash-based firmware which allows updates of all modules onsite. Analogue inputs auto-calibrate on power-up giving confidence in readings and a low data noise performance with over-sampled data.
With up to 8 expandable control axes and 32 data acquisition channels, you can have total confidence in your testing results. It has an exceptional data resolution and control with up to 20 bit effectiive auto-ranging data acquisition and a real-time digital computer control with 32 bit processing.
Three versions are available: for Servo-Hydraulic, Servo-Pneumatic and Servo-Electromechanical systems.


UTS Software

IPC Global's powerful and professional UTS Software draws upon over 30 years of advanced materials testing experience. IPC Global's test and control software is known for its simplicity in use, clarity of results and analytical power.
It was developed from expert knowledge of applications to run automated test routines and therefore speeds up testing. It is written in powerful, professional Delphi and features real-time graphs for monitoring the specimen under test; portable binary data files or sharing, reviewing and analysis; and "live" transducer levels display.
The purpose-built UTS applications have dialogue help boxes for automated test routines and easy-to-read graphic screens for test set up and reviewing. The test is totally programmable from the user.
