Description Demand for sustainable pavements increases day by day in asphalt paving industry. Efficient utilization of raw materials along with the economic issues is the main reason to increase the amount of Reclaimed Asphalt Pavement (RAP) in bituminous mixtures. Since RAP is essentially aged material, it is considered not to behave like a fresh pavement. Hence, many researchers have tried to seek for innovative technologies in order to enhance RAP characteristics to utilize it over again. The objective of this study is to investigate the influence of Waste Engine Oil (WEO) on properties of RAP and therefore to determine the optimum amount of RAP in order to achieve desired characteristics of mixture. In this study the mixtures including various contents of RAP, modified with optimum WEO content, were prepared together with control mixtures. Mixture characteristics such as air void contents and Marshall Stability and Flow values were determined to be checked with specification requirements. Indirect Tensile Strength (ITS) values were accordingly measured for mixtures containing high possible amounts of RAP modified with WEO and control specimens. Based on the developed evaluation indices (as the ratio of ITS results of RAP containing specimens modified with WEO to ITS results of control specimens) comparisons were made. The results showed that the use of WEO, as a rejuvenator for mixtures containing RAP, enhanced the amount of RAP used in bituminous mixtures.
