The Pavetest AMPT is a servo-hydraulically controlled testing machine specifically designed to perform the three asphalt tests developed under
NCHRP Projects 9-19 and 9-29; Dynamic Modulus, Flow Number and Flow Time. It is also the prescribed equipment in AASHTO T378-17
Standard Method Test for Determining the Dynamic Modulus and Flow Number for Hot Mix Asphalt (HMA) using the Asphalt Mixture Performance
Tester (AMPT). In addition, the Pavetest AMPT can also perform Direct Tension Cyclic Fatigue, Indirect Tensile Dynamic Modulus, Incremental
Repeated Load Permanent Deformation, Semi-circular bend, and Overlay Testing of Asphalt Mixtures.
The Pavetest AMPT is underpinned by Pavetest’s leading edge CDAS digital controller, TestLab software and a full complement of accessories,
hardware and software in perfect unison.
MAIN FEATURES

More reliable and environmentally friendly than
mechanical refrigeration & heating elements.
The unit can be equipped with water cooled TE
heating /cooling technology (optional).
Magnetically mounted on-specimen transducer
system, based on loose core LVDTs or optional
epsilon extensometers.
Gauge point fixing jig facilitates gluing gauge points
and the (top and bottom) platens for proposed AMPT
Direct Tension Cyclic Fatigue (S-VECD) Test.
Dynamic Verification Device.
DynafloTM HPS provides dynamic speed control of
the pump motor ensuring quiet operation.
Optional built-in, silent, air compressor with associated
air preparation equipment.
