Many researchers have been using Marshall Mixture design method for designing Hot Mix Asphalt (HMA) mixtures. The objective of this study is to evaluate the Marshall Mix properties for both types of mixtures using normal aggregate and carbide lime as filler material in ACW 14 mix. One using ordinate aggregate available at UNIMAS civil lab and another one the filler size of 75 μm was replace by carbide lime. The asphalt cement use varies from 4.5% to 6.5% and having penetration grades of 80/100. The mix were compare in term of Marshall Properties such as stability and flow; and volumetric properties are mixture density, Voids Filled with Asphalt (VFA), Voids in Mineral Aggregate (VMA), and Voids in Total Mix (VTM). Study show that the hot mix asphalt for the normal aggregate mix having a greater density but carbide mix having greater stability. The optimum binder content for the normal mix asphalt was 5.67% and 5.63% for the carbide mix. The ACW 14 for the carbide mix does not satisfied JKR requirement for flow, void in total mix and voids in aggregate filled with asphalt mean while the ACW 14 for normal only fail to satisfy the void in total mix and voids in aggregate filled with asphalt.
