Effectiveness of Polanga Oil as Rejuvenator for Asphalt with High RAP Content
Use of reclaimed asphalt pavement (RAP) in the full-depth recycling process is a cost-effective and environmentally responsible method. In this study, a non-edible oil available locally known as Polanga oil has been explored as a rejuvenator. Performance of the rejuvenated asphalt mixtures containing higher RAP content (30% to 70%) were studied. Rheological characterization of the rejuvenated binder was done with various tests such as rutting and fatigue test. Thermogravimetric analysis (TGA) was conducted used to study the thermal behaviour of the rejuvenated binder. Performance of the asphalt mixtures were assessed in terms of indirect tensile strength, moisture sensitivity, rutting, fatigue, and semi-circular bending test for low temperature cracking. The 5% dosage successfully rejuvenated the aged binder and also found to be thermostatically stable when exposed to temperature up to 230°C. Overally, the asphalt mixtures containing RAP up to 60% can be adopted without significantly affecting the performance.
