摘要
为了研究纤维对沥青胶浆性能的影响,分别对木质素纤维、聚酯纤维和玄武岩纤维的性能进行归纳分析,采用三大指标、车辙因子和拉伸断裂能等指标对纤维沥青胶浆的高温和低温性能进行研究分析。结果表明,三种纤维均会对沥青胶浆的性能造成不同程度的提升,木质素纤维的提升效果最佳。结合纤维自身热稳定性和经济性,可根据实际工程情况选择适宜的纤维类型。
In order to study the effect of fiber on the properties of asphalt mortar,the properties of lignin fiber,polyester fiber and basalt fiber were summarized and analyzed,and the high and low temperature properties of fiber asphalt mortar were studied and analyzed by using three indexes,rutting factor and tensile fracture energy.The results showed that the performance of the three fibers could be improved to varying degrees,and the lignin fiber had the best improvement effect.Combines the fiber's own heat Stability and economy,according to the actual engineering situation to choose the appropriate fiber type.
