Permanent deformation is an important factor in flexible pavement design. Through increasing traffic load and tire pressure most permanent deformation occurs in the upper layer rather than in subgrade.Wheel tracking is a popular HMA test, since it simulates the permanent deformation resistance of mixtures. The basic similarity of these devices is in using a cyclic wheel passing through the surface of specimens, and the cumulative rut after the proposed cycles is used as a measure of rutting potential. The wheel tracking test is undertaken using the Iran University of Science and Technology, ABRC Wheel Track machine, by applying 8000 cycles of wheel load of 50kg that turns around an axis and applies the wheel load to specimens. The test was done at
