摘　　要：纤维可显著提升沥青玛蹄脂碎石混合料的路用性能,但目前市售纤维种类繁杂,且不同纤维对混合料路用性能的影响存在差异。选用工程中常见的玄武岩纤维BF、木质素纤维CF及聚酯纤维PF,分别研究了3种纤维对沥青玛蹄脂碎石混合料路用性能(高温性能、低温性能、水稳性能及疲劳性能)的影响。通过绘制沥青玛蹄脂碎石混合料路用性能三元等高线图,直观展示了纤维复配对混合料路用性能的交互作用,进而提出纤维复配推荐方案。Fiber can significantly improve the road performance of asphalt mastic gravel mixture,but there are many types of fibers on the market,and the influence of different fibers on the road performance of the mixture is different.The influence of three kinds of fibers on the road performance(high temperature performance,low temperature performance,water stability performance and fatigue performance)of asphalt mastic gravel mixture is studied respectively by selecting the common basalt fiber BF,lignin fiber CF and polyester fiber PF in engineering.By drawing the ternary contour diagram of the road performance of asphalt mastic gravel mixture,the interaction effect of fiber compound on the road performance of mixture is intuitively demonstrated,so as to put forward the recommended fiber compound scheme.
