  In this paper, the effect of reclaimed rubber modification on the rheological characteristics of asphalt binders is studied. Reclaimed rubber with the extent of 12, 16 and 20 is added to the neat asphalt binder and then shear complex modulus is obtained for neat and modified asphalt binder via Dynamic Shear Rheometer (DSR) test. Using Christensen-Anderson- Marasteanu (CAM) model, master curves of shear complex modulus and phase angle are determined and compared for both neat and modified asphalt binders. Implementing master curves and the CAM model, a standard method for determining the high service temperature of asphalt binders is used and the effect of reclaimed rubber modification on rutting resistance is studied. Results have shown that adding reclaim rubber to the neat asphalt binder improves its rheological properties and rutting resistance. تفاصيل المقالة
