Different filler materials and gradation can change the bituminous performance in pavement. Filler materials act to improve the quality of mastic. Meanwhile, gradation can change the mechanical behaviour of bituminous mixture. Types of fillers that are used in this experiment are Ordinary Portland Cement (OPC), Pulverised Fly Ash (PFA), and Hydrated Lime. Two types of gradation are well-graded and gap-graded. This gave six different asphaltic concrete combinations where a series of testing are done to evaluate the characteristics of each bituminous mixture. Various test on the aggregate gradation, aphalt material and mineral filler are done before the Marshall Test in determining the best oil content. It was followed by the WESSEX Wheel Tracking Test, Beam Fatigue Test, Indirect Tensile Fatigue Test and Creep Test where the outcome are analyzed to determine which combination of filler and gradation relatively give better performance in reducing the occurrence of rutting and cracking. It shows that the combination of lime and well graded produced adequate void rate and flexibility, higher stability, lower rutting deformation rate, higher stiffuess, and longer fatigue life.
