This research mixed flyash as much as 1%, 2%, and 3%. The results of the study are the addition of fly ash from burning coalash as a filler for combustion residue from the Tanjung Enim PLTU for Asphalt Concrete WearingCourse (AC WC) asphalt mixture, the best results were obtained on a 2% mixture with the followingvalues: Stability value of 1240, 253 kg, VIM (Void In Mix) Value of 4.233%, VMA (Void in MineralAggregate) Value of 16.139%, VFB (Void Filled Bitumen) Value of 73.782%, Flow (melting) Value of3.63 mm and Marshall Quotient obtained at 329.280 kg/mm.
