Abstract
The applicability of recycled asphalt concretes, with the waste materials obtained in construction works of airport pavements, to airport pavement surface courses at taxiways was verified through this study. In laboratory tests on asphalt concretes with the maximum recycling rate of 70%, the recycled asphalt concretes are almost equivalent to new ones, regarding both flexural properties and anti-stripping properties, and the changes of properties due to accelerated aging actions become less as the recycling rate increases. The properties of full-recycled asphalt concrete is similar to those of recycled asphalt concrete with 70% recycling rate. Through the field observation on airport asphalt pavements with recycled asphalt concretes, the difference in properties between recycled and new materials is negligible.
