Maintenance and Overlay resolve medium distress, but reconstruction can be feasible and cost-effective because asphalt pavement deteriorated drastically with time and traffic. Therefore, pavements are required to be reconstructed or rehabilitated. Reuse of such construction waste is gaining popularity with the passage of time due to its benefits. The cost and shortage of virgin aggregate have encouraged the use of reclaimed asphalt pavement, and involved in regular practice in various countries around the world. Asphalt is 100% recyclable product in some states of US, but RAP usage has not yet been established in Pakistan. Therefore, in this research different percentages of aged aggregates are used in conjunction with virgin aggregates in asphalt mixtures. The virgin and RAP asphalt samples were then compared in terms of Marshall Stability, Rut resistance and indirect tensile strength (IDT). 22 samples including conventional and different RAP percentages were prepared for Marshall Stability, 10 samples for Rutting and 12 samples for IDT. It has concluded that the 60 percent RAP aggregate when used in conjunction with virgin aggregate in asphalt mixture gives improved Marshall Stability as compared to virgin aggregates when used in asphalt mixture, also the flow values of the 60 percent aged aggregate sample is neither open to rut of fatigue as compared to asphalt mixture prepared with virgin aggregate, and the indirect tensile strength of RAP mixture with 60% aged aggregate is high as compared to the asphalt mixture prepared with 100 percent virgin aggregates.
