Asphalt Mixture Performance Tester AMPT Pro


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, the AMPT PRO surpasses any other product on the market.
Fully complies with AASTHO TP9 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 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.

The Asphalt Mixture Performance Tester can be used as part of your Superpave performance based testing program.

This original Asphalt Mixture Performance Tester (AMPT) is the culmination of two National Cooperative Highway Research Program (NCHRP) projects. IPC Global has been involved in IPC Global equipment, and has been successfully evaluated by NCHRP.

Standard outfit
AMPT Pro includes, as standard, the following testing Modules (compression platens) which, however, have been 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 to 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 resistance of HMA to permanent deformation.

  • Static creep tests
  • Measure permanent deformation for rutting evaluation
  • Significantly improved ECU performance and innovation
  • The new Hydraulic Power Supply (HPS) uses inverter technology coupled with a high performance labyrinth bearing actuator to deliver 19 kN of force
  • Easy-to-use and ergonomic testing system
  • Interchangeable transducers and load cells with "plug and play" signal conditioners allowing for quick and easy transition of test set-ups
  • Clarity in results with the 3rd Generation Integrated Multi Axis Control System (IMACS2)
  • All-in-One computer control with the latest All-in-One touchscreen PC technology
  • Fully integrated and compact in design, a perfect solution for both static and mobile testing facilities
  • Data output is fully compatible with FHWA FlexMAT™ and FlexPAVE™ software
  • Optional air compressor that comes integrated
