The tire rubber obtained from end-of-life car and truck tires has been successfully recycled, among other applications, in the asphalt industry by providing a mean to get asphalt mixtures with superior performance. Textile fibres are another component derived from tire recycling typically disposed of in landfills or used in energetic valorisation. This paper wants to re-ignite interest in this secondary product by evaluating its use as a valuable resource in asphalt mixtures. Indirect tensile tests, dynamic modulus, fatigue resistance, and permanent deformation tests were performed on a series of AC14 asphalt mixtures manufactured with two binders, namely 50/70 and 35/50 pen, using several binder and fibre contents. The results indicate that incorporating fibres of tire recycling is not problem-free. Results have shown that can be advisable in pavement applications whenever the investigated fibre-modified mixtures allowed to incorporate at least 6.5% binder content with great benefit for pavement performance.

从报废汽车和卡车轮胎中获得的轮胎橡胶已成功回收，除其他应用外，还用于沥青行业，提供了一种获得性能卓越的沥青混合物的方法。纺织纤维是从轮胎回收中提取的另一种成分，通常在垃圾填埋场处置或用于能源增值。本文希望通过评估其在沥青混合物中作为宝贵资源的用途，重新点燃人们对这种二次产品的兴趣。对一系列 AC14 沥青混合料进行了间接拉伸试验、动态模量、抗疲劳性和永久变形试验，这些沥青混合料由两种粘合剂（即 50/70 和 35/50 笔）制造，使用多种粘合剂和纤维含量。结果表明，掺入轮胎回收纤维并非没有问题。
