| 摘 要： | 通过对不同级配类型、相同纤维掺量的沥青混合料进行车辙试验、残留稳定度试验和冻融劈裂试验,分析了级配类型对纤维沥青混合料路用性能的影响。结果表明,纤维可明显改善沥青混合料的高温性能和水稳定性能;不同级配类型对纤维混合料各项性能的改善有着显著的影响,SMA-13型纤维混合料改善效果最为明显,密级配AC型混合料随着公称最大粒径的增大,改善效果会逐步减弱;建议在纤维混合料配合比设计中,进行级配优化设计,以提高其路用性能。 |
| 关 键 词： | 沥青混合料 路用性能 纤维 级配类型 高温性能 水稳定性能 |

| Abstract: | Rutting test,residual stability test and freeze-thaw split test were used to measure the properties of asphalt mixture with different graduation and the same amount of fibers. The results were analyzed to obtain the influence of graduation types on the road performance of fiber-reinforced asphalt mixture. The results were summarized as follows: fibers could obvious improve the high temperature property and water stability of asphalt mixture; the graduation types have visible impact on the improvement of all... |
| Keywords: | asphalt mixture pavement performance fiber graduation type high temperature property water stability property |
