The extensive use of organic and virgin aggregates contributes to their resource exploitation. High priority must be given to the partial substitution of conventional aggregates with recyclable construction material, which must be environmentally responsible and should function equally too as the conventional material. Reclaimed Asphalt Pavements (RAP) is a great choice for the asphaltic wearing and asphaltic base courses of road pavements. In this research, the properties were determined for various combinations and proportions of virgin and aged asphalts. In this study, six blends which were the mixtures of virgin materials and RAP, were analyzed. The blends were designed with a wide variety of RAP blends from 0 to 100 percent by Marshall Method of design. The rutting performance of the blends was also determined in-order to check the deformation. The RAP content was combined with virgin aggregates in such a way that all the test samples had about the same gradation. RAP-containing mixtures showed significant variation and the properties indicated improvement with the increase in RAP material. The results show that up to 40 percent of RAP material can be used efficiently in the construction of wearing courses.
