| 摘 要： | 采用再生剂对不同老化程度的沥青进行再生,研究了再生剂对不同老化程度沥青再生性能的影响,并探讨了再生沥青的化学组成与物理性能之间的关系.结果表明,对于轻度老化沥青和中度老化沥青,当新沥青的用量分别为40%和60%时,掺入10%～15%的再生剂即可使再生沥青的物理性能满足新沥青的规范要求,而重度老化沥青由于其沥青质含量较高...

| Abstract: | Effect of rejuvenator on the reclaimed properties of aged bitumen of different aging degree is investigated and relationship between physical properties and chemical component of recycled bitumen is explored.The results indicate that for slightly and medially aged bitumen,when content of fresh bitumen is 40% to 60%,the physical properties of recycled bitumen can be restored to meet the fresh bitumen standards by adding 10% to 15% rejuvenator.However,for severely aged bitumen,only when content of fresh bitum... |
