Ageing is one of the small parts that causes damages and decreases to the flexible pavement construction strength, especially the asphalt concrete mixture. It will cause the mixture to be harder and more brittle, hence causing disintegration and cracking failures. Adding asphalt to the mixture is one of several ways to anticipate the ageing process in the asphalt mixture (Asphalt Institute, 1997). The objective of this research is to study the influence of adding asphalt to the bitumen ageing characteristic to the asphaltic concrete mixture. This research was performed by producing the STOA dan LTOA samples in accordance with the procedure of Strategic Highway Research Program (SHRP) at the project of A-003A. Variation of asphalt content were 0.25%, 0.50%, and 1.00% to the requirement from the optimum asphalt content (5.90%). The specification of asphaltic concrete mixture was based on Bina Marga 1987. The strenght of the mixture was measured using the Marshall, Immersion, and Cantabro test method. The results indicated that base on the Marshall characteristics, the maximum value of the addition of asp ahalt was 0.50% for the LTOA condition with the stability value of 1802.94 kg, flow value of 3.70 mm and MQ value of 487.77 kg/mm. At the STOA condition it was indicated that the strenght was decreasing at the addition of asphalt of 0.50%, but the stability value was 1371.82 kg, flow value of 3.50 mm, and MQ value of 391.70 kg/mm to satisfy the requirement. The Immersion Index value of the Immersion test of 48 hour was reached at the addition of asphalt of 0.50% and obtained 90.38% of the STOA condition and 69.10% of the LTOA condition. The percentage loss of mass value after 300 times of rotation showed that the addition of asphalt of 0.50% was obtained 4.64% for the STOA and 3.52% for the LTOA condition.
