摘要
玄武岩纤维是一种新型矿石拉丝纤维,将其应用到沥青路面工程中可提高路面综合使用水平。文章研究不同纤维掺量和长度下玄武岩纤维沥青混合料的路用性能,对比分析其高温稳定性、低温抗裂性和水稳定性。研究表明:玄武岩纤维掺量在0.4%、纤维长度为9mm时,沥青混合料的路用性能达到最佳。
Basalt fiber is a new type of ore drawing fiber,and its application to asphalt pavement engineering can improve the comprehensive use level of pavement.This article studies the road performance of basalt fiber asphalt mixture with different fiber content and length,and compares and analyzes its high-temperature stability,low-temperature crack resistance and water stability.The research shows that the asphalt pavement has the best road performance when the basalt fiber content is 0.4% and the fiber length is 9 mm.
