    Aging, specifically oxidation of the asphalt cement, has long been recognized as a major distress facilitator in asphalt concrete and, by extension, asphalt pavements. This process causes the material to stiffen and embrittle, and may lead to a higher potential for cracking. Despite its importance, there are many aspects of this phenomenon that are not completely understood after substantial
