摘　　要：如今的沥青路面暴露出很多问题,最主要的3种形式,即车辙永久变形、疲劳开裂和低温开裂。同时日常产生的很多废弃物质需要加以二次利用,因此可持续发展下再生纤维对再生沥青混合料的应用随之而生且越来越被关注。在国家双碳计划指导方针下,将蔗渣环保再生纤维、再生聚酯纤维、废旧轮胎再生纤维、Miber I型复合再生纤维、再生聚丙烯纤维这5种再生纤维分别掺入再生沥青混合料,对它们产生的路用性能以及一些力学冲击性能进行调研归纳总结,并对其未来的发展趋势进行研究分析。Nowadays,there are many problems exposed on asphalt pavement,and the three main forms are permanent rutting,fatigue cracking,and low-temperature cracking.At the same time,many waste materials generated in daily life need to be reused,so the application of recycled fibers in recycled asphalt mixtures under sustainable development has emerged and is increasingly attracting more attention.Under the guidance of the National Carbon Peak and Carbon Neutrality Plan,this article conducted research and summary on the road performance and some mechanical impact properties of recycled asphalt mixtures using five types of recycled fibers:slag environmentally friendly recycled fibers,recycled polyester fibers,waste tire recycled fibers,Miber I type composite recycled fibers,and recycled polypropylene fibers,and analyzed their future development trends.
