摘要
为了改善沥青混凝土的高温性能,在其中添加了由芳纶和聚丙烯两种纤维混合而成的福塔(FORTA AR)纤维.使用APA(沥青路面分析仪)分析了芳纶和聚丙烯这两种纤维在改善沥青混凝土高温稳定性方面的作用;使用环境扫描电子显微镜观察了沥青混合料中纤维的变化情况,从而进一步解释了纤维改善沥青混合料高温性能的机理.
Two blends of fiber（Kevlar and polypropylene） called FORTA AR were used to improve high temperature properties of asphalt mixture. Effects of Kevlar and polypropylene on improvement of high temperature properties were studied by APA（asphalt pavement analyzer）. Environmental scanning electron microscope was used to observe the changes of fibers in asphalt, and to explain mechanism that hybrid fiber reinforces asphalt mixture.
