A lot of waste nylon wires are produced during the production of brush wire products such as toothbrush, hairbrush, paintbrush, and so on. How to recycle and reuse waste nylon wire is a new problem This research presents a study of the behavior of waste nylon wire on Stone Matrix Asphalt (SMA) mixtures using Marshall design method. The specimens were tested using several common laboratory test procedures: Marshall stability test, rutting test, three-point flexural test and moisture susceptibility test. The related results indicate that waste nylon wire can effectively improve the high temperature stability, low temperature crack resistance and moisture susceptibility of SMA. Also, oil absorption, adhesion and the retarding effect of waste nylon wire on the crack propagation of asphalt mixture are attributed to the reinforcing mechanism. The research result can offer technical support for waste nylon wire used in road construction materials.
在牙刷、发刷、漆刷等刷丝产品的生产过程中会产生大量废弃尼龙丝。如何回收再利用废弃尼龙丝是一个新问题。本研究采用马歇尔设计方法，对废弃尼龙丝在沥青玛蹄脂碎石混合料（SMA）中的性能进行了研究。通过几种常见的实验室测试程序对试件进行了测试：马歇尔稳定度试验、车辙试验、三点弯曲试验和水敏感性试验。相关结果表明，废弃尼龙丝能有效提高SMA的高温稳定性、低温抗裂性和水敏感性。此外，废弃尼龙丝对沥青混合料的吸油、粘附及延缓裂缝扩展的作用归因于其增强机理。该研究结果可为废弃尼龙丝用于道路建筑材料提供技术支持。
