2294 Investigate the Aging Behavior of Asphalt Binders at Different Production Stages and During the Service Life of the Pavement

Asphalt mixtures undergo aging during production, placement, and throughout the service life of the pavement, which affects the pavement performance, and ultimately results in pavement distresses. To improve the asphalt mix design process and extend the pavement life, it is important to evaluate the rate of aging and quantify its impact on the mixture properties. A comprehensive study of asphalt aging includes both a lab and field study of different asphalt mixtures representing a wide range of materials and mix designs in the state of Oklahoma.
