Asphalt Mixture Performance Test – Pavement Interactive

Overview. The asphalt mixture performance tester (AMPT) is the companion performance test for use with the Superpave mix design procedure. Although the original SHRP asphalt research program was essentially done by 1993, it did not include a performance test for use with the rest of the Superpave mix design procedure.

HMA Performance Tests – Pavement Interactive

Performance tests are used to relate laboratory mix design to actual field performance. The Hveem (stabilometer) and Marshall (stability and flow) mix design methods use only one or two basic performance tests. Superpave is intended to use a better and more fundamental performance test. However, performance testing is the one area of Superpave yet to be implemented.

Performance Tests for Rutting – Pavement Interactive

Rutting is apparent in the wheelpaths of this street. This is one reason the Superpave mix design method does not require a specific performance test for rut resistance. Earlier approaches like the Hveem method and the Marshall method do incorporate simple mechanical tests, such as the Hveem stabilometer or the Marshall stability and flow test, in which a load is applied and the resistance of ...
