Performance Characteristics of Asphalt Mixes Containing High Percentage of RAP Material
Major challenges of using reclaimed asphalt pavement (RAP) in asphalt pavement are the stiffness of RAP because of oxidation of asphalt binder with the age and lack of performance data containing a high percentage (>30%) of RAP in hot mix asphalt (HMA). This research paper is aimed to investigate the feasibility of high percentage 60% RAP in asphalt mixes in the surface course of pavement. Designed mixes were developed for control mix and RAP mixes with two different rejuvenators to evaluate the performance parameters like indirect tensile strength, susceptibility to moisture damage, stiffness, cracking resistance, rutting, and fatigue. From the study, it is concluded that RAP mix with tall oils rejuvenator was better in terms of moisture resistance and rutting performance, while RAP mix with aromatic extract rejuvenator was better in terms of fatigue cracking. However, fatigue performance was better in control mix than RAP mixes.
