Regenerated fan blade fiber asphalt mixture and preparation method thereof
The invention discloses a regenerated fan blade fiber asphalt mixture and a preparation method thereof. The preparation method of the regenerated fan blade fiber asphalt mixture comprises the following steps: cutting, crushing and milling waste fan blades to obtain regenerated fan blade fibers; determining a mix proportion according to the gradation of the target asphalt mixture, and determining the use amount of asphalt and regenerated fan blade fibers; the regenerated fan blade fibers are pretreated, and regenerated fan blade powder is screened out; the aggregate, the asphalt and the mineral powder are placed in a drying oven to be preheated for 2-4 h; and sequentially adding the aggregate, the asphalt, the regenerated fan blade fiber and the mineral powder into a stirring device, and stirring for 3-5 minutes to prepare the regenerated fan blade fiber asphalt mixture. According to the invention, the regenerated fan blade fiber is doped into the asphalt mixture by adopting a dry method, so that the low-temperature cracking resistance, fatigue resistance and high-temperature deformation resistance of the asphalt mixture are improved, the performance of an asphalt pavement is improved, and meanwhile, an effective method is provided for recycling fan blades.
本发明公开了一种再生风机叶片纤维沥青混合料及其制备方法，该再生风机叶片纤维沥青混合料的制备方法包括：通过对废旧风机叶片进行切割、破碎、铣削等得到再生风机叶片纤维；根据目标沥青混合料级配确定配合比，确定沥青及再生风机叶片纤维的用量；将再生风机叶片纤维进行预处理，筛出再生风机叶片粉末；将集料、沥青及矿粉放置于烘箱中预热2‑4h；再将集料、沥青、再生风机叶片纤维及矿粉依次投入搅拌装置中拌合3‑5min，制成再生风机叶片纤维沥青混合料。本发明采用干法将再生风机叶片纤维掺入沥青混合料中，从而提升沥青混合料抗低温开裂、疲劳及高温变形的能力，用于改善沥青路面的性能，同时为风机叶片的回收利用提供了有效方法。
