The Pavetest AMPT (Asphalt Mixture Performance Tester) is a compact, fully self-contained servo-hydraulically controlled testing system designed for advanced asphalt mixture performance evaluation. It supports the Dynamic Modulus, Flow Number, and Flow Time tests developed under NCHRP Projects 9-19 and 9-29.

The AMPT is fully compliant with AASHTO T400, T411, TP132, TP134, T378, and TP107 and can perform a broad range of tests, including Indirect Tensile Dynamic Modulus, Incremental Repeated Load Permanent Deformation, Semi-Circular Bend, Overlay Testing, and Fatigue Analysis.

The system integrates Pavetest’s CDAS2 digital controller and TestLab software for full data acquisition, control, and automated analysis.
