摘要：Reducing the service life of the road pavement can be caused by weather effects in addition to increased traffic load. This study investigates the benefits of using Buton asphalt as a material additive. Buton asphalt additive by 20%, 25%, 30% and 40% is added to the bitumen pen 60/70 to get aspalt concrete wearing course (AC-WC) mixture. The evaluation has used the results of marshall standard, marshal immersion, indirect tensile strength and wheel tracking test at optimum bitumen content 5.9%. Wheel tracking test was performed on conditions at 30 ° C and 60 ° C of the 4000 cycle. The result in this study that, the addition of additives in the virgin asphalt has increased the softening point, lower the value of penetration, increased penetration index and lower ductility values??. Hot-mix Buton Aspalt Modified (HMBAM) have shown an increase in resistance to deformation of 1.24 times compared to Hot-mix Asphalt (HMA). Tensile Strength Ratio (TSR) increased 2.6% more resistance to the effects of temperature. The addition of additive content of 25% is recommended in order to avoid reduction in ductility lower.
