ABSTRACT
Pavement recycling has become a common practice for many states in the U.S. While material properties of concrete containing recycled aggregates (reclaimed asphalt pavement and recycled concrete aggregate) as virgin aggregate replacements have been extensively characterized, very little effort has been made to address concrete pavement design concerns and assess potential sustainability benefits of this application. In this study, recommendations from a pavement design perspective for recycled aggregates based concrete pavement were reviewed and summarized. Two life cycle assessment case studies were presented. Based on the results, it is concluded that the use of recycled aggregates in concrete pavement not only is a technically sound strategy, but also can lead to significant sustainability benefits.
