Abstract
Utilizing the reclaimed asphalt pavement (RAP) materials for production of asphalt mixtures are environmentally friendly and economical. One necessary step towards arriving at an efficient use of these materials is the understanding of undesired inherent characteristics of RAP such as aged (stiff) asphalt binder and inconsistent aggregate properties. Previous studies on the rejuvenating agents have reported a fairly high improvement in the engineering properties of asphalt mixtures with the high contents of RAP. The paper presents the effects of various rejuvenators on the engineering characteristics of the asphalt mixtures containing high percentage RAP (65%) with two different scales of mixture: asphalt concrete (AC) and fine aggregate matrix (FAM). Resulting experimental tests of viscoelastic stiffness and cracking behavior of asphaltic materials in both AC and FAM scales were compared.
