Determination of the Surface Oxidation of Pavement Preservation Treatments

Oxidation, a process in which asphalt binder reacts with oxygen, occurs in asphalt pavement, reducing its longevity, durability and performance. The role of oxidation in pavement preservation treatments, however, is little understood. This project seeks to determine the impact of environmental aging on pavement preservation treatments. Researchers will quantify the extent of aging on asphalt binder used in chip seal and microsurfacing treatments and, if aging is a significant factor, propose ways to mitigate it. Obtaining data on the role of aging in pavement preservation will allow the Illinois Department of Transportation to better predict the lifespan of pavement and help to lessen aging, improving the longevity of pavements and minimizing disruption to drivers for maintenance, rehabilitation or reconstruction activities.
