The AMPT-15 is a servo-hydraulic Asphalt Mixture Performance Tester designed to perform dynamic modulus, flow number and flow time tests as specified by NCHRP, AASHTO and other relevant standards. The AMPT-15 is designed to maximize test efficiency through intuitive design and innovative software.

The tests can be performed at a range of temperatures and frequencies to simulate traffic loading and environmental conditions. The test results are used as design inputs in the mechanistic pavement mix design. The AMPT-15 automatically performs the specified standard tests with minimal user intervention.

GCTS offers a remote test monitoring package, which allows the user to check the status of any test via a smartphone app.
