Abstract—Asphalt Concrete – Wearing Course (AC-WC) is a surface layer of flexible pavement which have direct contact with vehicle wheel. One of the surface layer damage categories is the wheel track (rutting). In this research, the experiment was done by using industrial waste of granite stone production in the form of dust as filler in the AC-WC mixture. The variation of filler content used are 3%, 4.5%, 6%, 7.5% and 9% with cement filler as comparator. The test was conducted by using wheel tracking machine on temperature of 60˚C, 45˚C and 30˚C. The test result shows that the optimum filler content using granite dust in the AC-WC mixture is 3%. Meanwhile the optimum filler content on the asphalt concrete using cement filler is 7.5%. Thus, it shows that the higher temperature cause the ability of maintaining the wheel track decreased. Furthermore if looking at the relation between dynamical stability, deformation depth and deformation velocity on filler concentration is not linear.
