General description
General description
IPC Global, the researcher's choice for advanced asphalt testing equipment has again set the benchmark for innovation and performance with the new AMPT Pro. Designed with the latest technologies and product developments to ensure that it surpasses any other product on the market, fully complies with AASTHO TP79 and can perform the three asphalt tests of NCHRP Projects 9-19 and 9-29 - Dynamic modulus, Flow Number and Flow time with ease. In addition it can also perform Uniaxial Fatigue/SVECD, Overlay test, Semi-Circular Bend, Indirect Tensile Dynamic Modulus, iRLPD and Small Diameter Dynamic Modulus and SVECD tests with the additional of optional hardware accessories.

This original Asphalt Mixture Performance Tester (AMPT) is the culmination of two National Cooperative Highway Research Program (NCHRP) projects. IPC Global have been involved in these projects from the beginning with development work done on IPC Global equipment, and it has been successfully evaluated by NCHRP.

Standard outfit
AMPT Pro includes, as standard, the following testing Modules (compression platens) which, however, have to be completed with the transducer kit accessory.

Dynamic Modulus E to AASHTO TP79 and NCHRP 9-29
A performance.related property, for asphalt mixture evaluation and charachterising the stiffness of HMA. It is an important input parameter for AASHTO "mechanistic-Empirical Pavement Design Guide".
  • Creates master curves for structural design
  • Assess modified binders and local materials
  • Forensisc analysis of pavement failure
Flow Number to AASHTO TPXX and NCHRC 9-29
Flow number is related t the resistance of HMA to permanent deformation.
  • Repeated load creep tests
  • Evatluate rutting
  • Accurate simulation of actual loading
Flow time to NCHRP 9-29
Flow time is a quick and simple measurement of the resistence of HMA to permanent deformation.
  • Static creep tests
  • Measure permanent deformation for rutting evaluation

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.
