在沥青混合料中添加纤维不仅改善了自身的路用性能,同时其结构参数也会发生相应变化。本文以两种常用的路用纤维为基础,通过室内试验研究,分析纤维的类型和剂量对沥青混合料的物理、力学参数以及其路用性能影响的特点和变化规律,揭示了纤维沥青混合料力学参数的特点和路用性能的本质,提出纤维沥青混合料在设计、施工提高工程质量的措施和方法,为纤维沥青路面的推广应用提供参考。
Addition of fibers to the asphalt mixture not only improves its road performance, but also its structural parameters change accordingly. In this paper, based on two kinds of commonly used fiber for road use, the characteristics and changes of the influence of fiber type and dosage on the physical and mechanical parameters of asphalt mixture and its road performance are analyzed through laboratory experiments. The results show that fiber asphalt mixture The characteristics of mechanical parameters and the nature of road performance, the measures and methods to improve the quality of fiber asphalt mixture in design and construction are put forward, which will provide reference for the popularization and application of fiber asphalt pavement.
