路用纤维对 SMA 沥青混合料中矿料间隙率的影响

摘要

通过分析 SMA 混合料中常用的纤维类型，比较了不同路用纤维在沥青混合料中的使用性能，并通过马歇尔试验，研究了SMA 混合料矿料间隙率随纤维种类和掺量变化的增减规律，得出了一些有意义的结论。%By analyzing commonly fiber types in SMA mixture to compared the performance of different fibers in the asphalt mixture. By marshall experiment,study the Voids in Mineral Aggregate rule change with the fiber type and dosage varies of SMA mixture. It has obtaimed some signif-icative conclusion.
