This research evaluated the stiffness and permanent deformation properties of typical Wisconsin Department of Transportation (WisDOT) asphalt mixtures using the Asphalt Mixture Performance Tester (AMPT) and associated test and analysis procedures. Dynamic modulus master curve and flow number data were collected for 12 different good performing asphalt mixtures representing typical mixture design practice in Wisconsin. The data were analyzed to determine the sensitivity of the AMPT tests to changes in key mixture design factors associated with rutting resistance. A database of dynamic modulus master curve and flow numbers was assembled for use in future mechanistic pavement design related efforts.
