Abstract

The present study aimed to investigate the properties of reclaimed asphalt pavement (RAP) mixes to determine their suitability for preparing conventional hot mix asphalt (HMA) for wearing courses. To effectively recover the properties of the aged binder, the RAP was combined with two waste materials such as waste engine oil (WEO) as a rejuvenator and crumb rubber (CR) as a binder modifier. The effect of WEO on the rheological and physical characteristics of the extracted aged binder was investigated by analysis. Five different HMA mixes were prepared with different percentages of RAP aggregate replacing virgin aggregates at 0%, 30%, 50%, 70%, and 100%. The flow, volumetric properties, and Marshall stability tests were examined in this study. Every RAP mix showed adherence to the 8.0 kN minimum stability requirement. The Marshall flow showed an increasing trend as the binder and RAP content increased. Notably, each mix met the minimum (2.0 kN/mm) Marshall quotient criteria. The results demonstrated that the optimum binder content (OBC) gradually decreased as the RAP content rose. With the increase in RAP content, there was a noticeable increase in the binder saving rate. Particularly, 79.7% less binder was used in the R100 mix compared to the R0 mix. Statistical analysis clearly showed that the amount of RAP and binder significantly influences the effectiveness of the mix’s design. the effectiveness of the mix’s design. Therefore, the combination of CR and WEO allows for the creation of HMA compositions with up to 100% RAP.
