Evaluation of Performance of Reclaimed Asphalt Pavement Mixtures Using Acetone as Rejuvenator
Reclaimed asphalt pavement (RAP) is the removed asphalt mixture, which has many advantages like economical, reduces landfills and greenhouse gases emission, and is sustainable. So, it is significant to use RAP in stone matrix asphalt (SMA) mixtures, whereas SMA mixture is proven to be rutting resistant mixture. In this study, acetone is used as a rejuvenator and that may improve the aged binder properties. From the test results, it is seen that acetone reacted with aged binder and improved the blending up to 20% RAP content and increased the fracture and moisture resistance. It is confirmed that acetone removed the aged binder from the RAP and enhanced blending process (mixing of RAP and virgin asphalt) up to 20% RAP content. However, acetone failed to improve the moisture and fracture resistance of 30 and 40% RAP content mixtures. About 9% acetone dosage is optimum dosage to enhance the performance of the RAP-incorporated SMA mixture. It is recommended that further detailed investigation is needed to understand the behaviour of Acetone on the RAP.
