Substandard aggregates is aggregates which isn’t required at paving specification, such as specific gravity, plasticity, absorption and abrasion that will effect stickness at asphalt mixture. The objective of this research is to evaluate the influence of substandard aggregate-high abrasion value (>40%) were varied by standard aggregates (abrasion ≤40%) on a continuous gradation asphalt mixture (AC-BC) to the value of stiffness and deformation. Properties of aggregates were tested and compared using specification of Bina Marga 2010, while the mix of characteristics obtained through Marshall Test, Resilient Modulus using UMATTA and permanent deformation using Wheel Tracking Machine ( WTM ). Percentage of substandard aggretgates and standard aggregates in this research is 100-0, 80-20, 60-40, 50-50 dan 0-100. Marshall test result on the variation of 60-40, 50-50 dan 0-100 indicate that te addition of standard aggregate improving the Marshall Stability and residual strengh index, but the residual strenght index velue is still below of spesification. UMATTA test result at 25C and 45C temperature variation of 60-40, 50-50 dan 0-100 that mix stiffness ( Resilient Modulus ) higher. Test result of permanent deformation using WTM at temperature 45°C dan 60°C, the highest dynamic stability value at 50-50 mixture.
