Abstract
The use of Reclaimed Asphalt Pavement (RAP) to produce asphalt concrete is becoming more and more popular in the world because of its technical, economic and environment. However, when a high RAP is used, causing a negative effect on the performances of the mixtures. Therefore, rejuvenators are used to improve the properties of bitumen and to recycle asphalt mixtures. This paper presents a study on the influence of the type and content of the rejuvenators on the penetration and the softening point of bitumen. The types of bitumen were evaluated including the virgin bitumen, aged bitumen recovered from RAP and bitumen blends (including virgin bitumen, RAP aged bitumen with the recycled binder ratio (RBR) of 0.3, and rejuvenator). Two rejuvenators used in the study are petroleum-based recycling agent (HS1 rejuvenator) and vegetable oil-based (Prephalt@FBK rejuvenator) with different contents from 0%, 4%, 8% and 12%. The obtained results have shown the effectiveness of rejuvenators in restoring the physical properties of bitumen. In order to meet the requirements of the penetration and softening point as bitumen 60/70, the rejuvenator content should be about 9.0% with HS1 and about 5.0% with Prephalt@FBKReferences
