Abstract

Marshall Mix design was the conventional method to design the hot mix asphalt (HMA).This paper describes the Marshall Mix design ACW20 using two difference material. One using ordinate aggregate available at UNIMAS civil lab and another one the filler size of 150 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 5.13% and 5.63% for the carbide mix. The ACW 20 for the normal mix aggregate does not satisfied JKR requirement for flow and void in total mix mean while the ACW 20 for carbide only fail to satisfy the void in total mix. Carbide mix showing higher stability value hence it has the potential martial for replacing ordinate fine aggregates.
