摘要
为研究不同形态纤维对沥青混合料路用性能的影响,采用车辙试验、低温小梁试验、IDEAL开裂试验和冻融劈裂试验对4种不同纤维沥青混合料进行试验研究。试验结果表明:玄武岩纤维沥青混合料整体性能要优于木质素纤维沥青混合料,但玄武岩纤维的形态对沥青混合料的影响不大,木质素纤维的形态对沥青混合料的高温稳定性(动稳定度提升了8.8%)和中温抗裂性(抗裂指标提升了17.9%)影响较大,对低温抗裂性和水稳定性影响较小。
In order to study the influence of different forms of fibers on the road performance of asphalt mixture,rutting test,low temperature trabecular test,IDEAL cracking test and freeze-thaw splitting test were used to study four different fiber asphalt mixtures.The test results show that the overall performance of basalt fiber asphalt mixture is better than that of lignin fiber asphalt mixture,but the morphology of lignin fiber has a great influence on the high temperature stability(dynamic stability increased by 8.8%)and medium temperature crack resistance(crack resistance index increased by 17.9%)of asphalt mixture,and has little effect on low temperature crack resistance and water stability.
