摘　　要：为探究沥青混合料中复掺木质素纤维和玄武岩纤维的效果,明确复掺玄武岩和木质素纤维的最佳复掺比例,设计室内试验,取不同比例玄武岩纤维和木质素纤维并分别制备纤维改性SMA-13沥青混合料,测试各组沥青混合料的路用性能。试验结果显示:高温性能方面,玄武岩纤维改良效果相对更佳,低温性能方面,木质素纤维改良效果相对更佳;综合考虑沥青混合料路用性能,认为玄武岩与木质素纤维复掺质量比为1∶1时效果最佳。研究结果为复掺两种不同成分纤维的SMA沥青混合料设计提供了应用指导。In order to explore the effect of mixing lignin fiber and basalt fiber in asphalt mixture,and determine the optimal mixing proportion of mixing basalt fiber and lignin fiber,laboratory experiments were designed to prepare fiber modified SMA-13 asphalt mixture with different proportions of basalt fiber and lignin fiber respectively,and the road performance of each group of asphalt mixture was tested.The results show that basalt fiber has better improvement effect at high temperature and lignin fiber has better improvement effect at low temperature.Considering the road performance of asphalt mixture comprehensively,it is considered that the best effect is when the mass ratio of basalt and lignin fiber is 1∶1.The research results provide guidance for the design of SMA asphalt mixture mixed with two different fiber components.
