Laboratory and Field Studies of Recycled Asphalt Concrete for Airport Pavement Surface Courses

This study examines the use of recycled asphalt concrete for airport pavement surface courses through laboratory tests and field experiments. Two key points were initially subjected to intensive study in the laboratory: the effect of rejuvenating agents on recycled asphalt concrete performance and the possibility of increasing the proportion of old aggregate in the total aggregate. Recycled asphalt concrete was then experimentally applied to airport pavement surface courses in actual use. Almost no difference was found between the performance of recycled and new asphalt concretes in field observations. In addition, the applicability of 100% recycled asphalt concrete to airport pavements, the possibility of re-recycling asphalt concrete, and the influence of old aggregate quality on recycled asphalt concrete performance were investigated in an effort to promote the recycling of asphalt concrete. It is concluded that asphalt concrete containing up to 70% old aggregate obtained from airport pavements can be used for the surface courses of airport pavements. Moreover, investigation of certain additional measures shows that further promotion of asphalt concrete recycling is possible. For the covering abstratc of this conference see ITRD number E215163.
