短切玄武岩纤维沥青混合料路用性能研究

为探讨短切玄武岩矿物纤维在增强沥青混合料路用性能方面的适用性,以聚酯纤维为对比对象,通过马歇尔试验、浸水马歇尔试验、高温车辙试验,评价了短切玄武岩纤维沥青混合料的路用性能,并根据复合材料理论探讨了玄武岩纤维改善沥青混合料路用性能的基本原理。研究发现短切玄武岩纤维的最佳掺量为0.3%。并且其性能优于聚酯纤维;短切玄武岩纤维沥青混合料的高温抗车辙能力和水稳定性能均优于聚酯纤维沥青混合料,可作为提高沥青路面综合性能的添加材料用于道路工程中。

Research on pavement performance of the short-cut basalt fiber-reinforced asphalt mixture

To discuss the applicability of the short-cut basalt fiber in reinforcing the pavement per- formance of asphalt mixture,compared with the polyester fiber,by marshall test,water stability test,and wheel track test,the performance of the short-cut basalt fiber-reinforced asphalt mixture were evaluated,and then study the basic principle of fiber reinfocing asphalt mixture through the the- ory of composite.The results show that the optimum mix amount of the short-cut basalt fiber is 0.3%,and it has better perfo...
