The document evaluates the performance of using wooden charcoal as a filler in stone matrix asphalt (SMA). SMA is a gap-graded asphalt mixture made of 70-80% coarse aggregate that provides strength and rut-resistance. The study examines the Marshall properties of SMA mixtures containing different fillers like stone dust, cement, and fly ash, and compares them to mixtures containing wooden charcoal filler. The optimum binder content is determined using the Marshall method. Previous studies on SMA properties related to mix design and the effect of mineral fillers on SMA performance are also reviewed. The main objective is to evaluate the suitability of wooden charcoal as a filler in SMA.
