GENERAL DESCRIPTION

IPC Global, the researcher's choice for advanced and 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 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 testingprogram.

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
