Current research status of the impact of recycled fibers on recycled asphalt mixtures under sustainable development
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.
