Durability and Performance of Reclaimed Asphalt Pavement with Rejuvenators: A Review

Author(s) Mr. Amit Kumar, Mr. Abhay dalal

Abstract Reclaimed asphalt pavement (RAP) has become a widely used material in road construction because it helps reduce costs and supports environmental goals. However, a key problem with using RAP at high content levels is that the existing binder in RAP becomes old and hard over time, which reduces the overall quality of the new pavement. Rejuvenators are chemical agents that are added to RAP mixtures to soften the aged binder and restore its original properties. This paper reviews the published journal literature on the durability and performance of RAP mixtures treated with different types of rejuvenators. The review covers topics such as binder chemistry, mechanical performance, fatigue resistance, rutting behavior, moisture sensitivity, and environmental benefits. Studies show that properly designed RAP mixtures with rejuvenators can achieve performance close to that of virgin asphalt mixtures. Bio-based rejuvenators such as soybean oil and tall oil have shown CO2 reductions of 38 to 48 percent compared to standard mixtures. The review also identifies research gaps and suggests future directions. Overall, this paper shows that rejuvenator technology is a promising tool for making high-RAP pavements both durable and sustainable.
