Abstract
Petroleum crude oil, the prime source of asphalt binder, originates from many naturally occurring crude sources, which vary widely in chemical compositions. These compositions are defined as Saturates, Aromatics, Resins, and Asphaltenes (SARA) fractions. Physical properties of an asphalt binder are closely linked to its crude-inherited SARA fractions. Thus, asphalt binders differ significantly from one another, while they are intended to serve the same way under a specified traffic loading intensity and temperature. To serve this need, asphalt binders are often modified chemically. Sometimes, Reclaimed Asphalt Pavement (RAP) is added to this binder because of the limited supply of virgin binders. SARA fractions of two crude-different binders have been studied to find correlations, if any, with their mechanistic properties. Both were modified with acid and polymer. One of them was blended with RAP as well. Some of their mechanistic properties were found to be well correlated with their SARA fractions.
