【摘要】 再生沥青有一般道路沥青所不具备的特殊性,对再生后沥青抗老化性能的考察却并无统一认可的方法。本文采用老化指数法和软化点速率升高常数法,分别考察了沈阳-铁岭(沈铁)和沈阳-本溪(沈本)公路段再生沥青及其原沥青辽河AH-90的抗老化性能。实验结果证明了这两种方法的可靠性。更多还原

【Abstract】 Regenerated asphalt has special performance compared with the general asphalt, however, there is no unitary method to investigate the anti-aging performance of regenerated asphalt. The anti-aging performance of two regenerated asphalt, from Shentie and Shenben highways, as well as their original asphalt—Liaohe AH-90, are investigated by anti-aging index method and softening point rate elevated constant method. The reliability of the two methods are certified by result of experiment.更多还原
