Previous researched had shown that modified bitumen has the ability to offer improved performance over conventional bitumen. Due to the increasing number of traffic loads and volume, used of conventional bitumen is not enough to prevent the pavement from deterioration. Nowadays, modified asphalt technology is used by researcher and manufacture to improve the performance of asphalt pavement. This research presents a performance of asphalt pavement using Sasobit as an additive. In this study, the percentages of Sasobit were varied from 0%, 2.5%, 5.0%, 7.5% and 10%. The aggregate gradation that considered in this study is dense graded (asphaltic concrete with 14 mm nominal maximum aggregate size – AC14). The tests that conducted were bitumen penetration, softening point, Marshall mix design and Cantabro test. The result shows that when amount of Sasobit increases, the penetration was decreased and softening point increased. The performance of asphalt pavement was significantly affected with the addition of Sasobit. Sasobit modified mixes were found to improve both durability of the asphalt pavement and its deformation resistance. In this study, the optimum Sasobit content was found 2.5%
