ABSTRACT
With the use of high percentage Recycled Asphalt Pavement (RAP), there is an increasing concern over how much of the aged binder in RAP that can be blended into virgin binder. In this study, the RAP binder mobilization rates of nine mixtures from asphalt plants in Tennessee were tested using fluorescence microscopy. A multiple regression was conducted to investigate the relation between mobilization rate and mixed conditions. Results indicates that mixing and delivery temperatures had significant influence on the mobilization rate of RAP binder.
