EVALUATION OF RECYCLED PROJECTS FOR PERFORMANCE (WITH DISCUSSION)

In general, this study found that recycled pavements containing reclaimed asphalt concrete materials in the range of 20 to 50 percent by weight of the mixture in both binder and wearing course mix performed similarly to conventional pavements for a period of six to nine years after construction. These findings are based on the selection of five recycled pavements and five conventional pavements selected to be of similar section and mix design, traffic and (if possible) constructed by the same contractor. Only one pavement contained a recycled section and a control section on the same project.
