LABORATORY PERFORMANCE OF RECYCLED ASPHALT CONCRETE
Addition of rejuvenating oils to aged, dry asphaltic pavement materials to restore them to their original condition is a practice currently being used on many construction projects. Typically, the effect of renjuvenation is measured using standard mix design procedures such as stability. This research was aimed at providing information on the behavior of rejuvenated mixtures when subjected to accelerated aging such as repeated freezing and thawing and sustained high temperature. The nondestructive resilient modulus test was used to monitor the change in recycled mix from an old pavement, new mix made with virgin asphalt, and old mix rejuvenated with two commercially available admixtures. Results indicated that old mixtures continued to age rapidly and the rejuvenated mixtures behaved similarly to virgin mixtures. (Author)
