| Abstract: | TFOT aging has been conducted on SBS modified bitumen at different aging time.The aged binders are then recycled by blending with rejuvenating oil.Aging has been carried out again on both asphalt mixtures of fresh binder and recycled binders.The aging behavior for the two kinds of asphalt mixture has been compared according to performance test on the mixtures.As a result,the durability of recycled SBS asphalt mixture has been evaluated. |

| Keywords: | recycled asphalt mixture re-aging behavior evaluation of durability |
