In order to investigate the influence of recycled asphalt content on high and low temperature properties of foamed warm-mix asphalt, the softening point test, dynamic shear rheological test and BBR test are conducted with 0%, 20%, 40%, 60%, 80% recycled asphalt. The results indicate that, with the increase of recycled asphalt content, the softening point, rutting factor and fail temperature of the foam warm-mix asphalt increase gradually, and the high temperature performance of the asphalt binder is obviously improved. The low temperature crack resistance of foamed asphalt decreases with the increase of the proportion of recycled asphalt content. When the recycled asphalt content is more than 40%, the creep stiffness and creep strain rate of the foamed asphalt cannot meet the requirements of the specification, and the low temperature cracking performance is poor. So the proper amount of recycled asphalt is less than 60%.
