| 摘 要： | 沥青混凝土的疲劳性能在道路长期安全舒适运营过程中起着至关重要的作用.选用控制应力加载模式的室内间接拉伸疲劳试验,对Superpave 13密级配沥青混合料在纤维掺量分别为0、0.15％、0.25％、0.35％时的疲劳性能进行了试验研究.结果表明:沥青混合料疲劳寿命随着纤维掺量的增加而增加,但掺量过多则会影响纤维分散均匀... |

| Abstract: | Fatigue performance of asphalt concrete plays an important role on road safety and comfort during long-term operation.Based on previous studies,using stress controlled loading mode,laboratory indirect tensile fatigue tests are performed to evaluate the fatigue performance of Superpave 13 dense-gradation asphalt mixture at 0,15,25 and 35 percent of fiber content.The results of tests show that the fatigue life increases with the fiber content,but too much content would affect dispersion uniformity of fibers,w... |
