为增强玄武岩纤维(BF)在沥青中的加筋及增强效果,采用1.0 mol /L及2.5 mol /L的NaOH溶液对BF进行表面处理,通过环境扫描电镜和红外光光谱试验对其表面细观形貌进行了细观观测,原样BF表面光滑,NaOH处理后的BF呈现明显的皮芯结构,且随着NaOH的浓度及处理时间的增加,BF的羟基含量越高;通过软化点、5 ℃延度、车辙因子及环境扫描电镜试验等,研究了玄武岩纤维沥青的高、低温性能及拉拔断口形貌,随着BF的侵蚀程度越大,玄武岩纤维沥青性能越好,且得到了NaOH对BF侵蚀的最佳处理时间和浓度分别为45 min、2.5 mol /L。

In order to enhance the reinforcement and strengthening effect of basalt fiber（ BF） in asphalt,surface treatment of BF by 1. 0 mol/L and 2. 5 mol/L Na OH solution was performed. The surface morphology of BF was observed by environmental scanning electron microscopy（ ESEM） and infrared spectroscopy（ IR） test. The results show that the surface of original BF was smooth,and BF showed a clear core structure by Na OH solution treated from the ESEM. With the increase of Na OH solution concentration and treatment time,the results show that the h...
