With the increase of solid wastes, officials in Ras Al Khaimah (RAK), United Arab Emirates (UAE) are evaluating reuses of these materials rather than being dumped in landfills. Furthermore, asphalt pavements in RAK are failing prematurely due to heavy and slow traffic accompanied with high temperatures during the summer. To assist in the efforts of solving these problems, this study was conducted to investigate the effects of adding waste plastic fibers to Hot Mix Asphalt (HMA). Tests were conducted on a standard HMA with two asphalt binder grades and two waste plastic fiber contents (0.5 and 1% by weight of mix). Results showed that HMA fracture resistance at −10 and 21.1°C temperatures and rutting resistance at a 54.4°C temperature increased by the addition of waste plastic fibers. For an overall improvement in performance of asphalt pavement, the optimum waste plastic fiber content was found to be 0.5% by weight of mix. Thus, by adding waste plastic fibers to HMA, an improvement of performance (rutting and cracking resistances) of asphalt pavements and a positive effect on the environment could be achieved by the reuse of discarded plastic waste.

随着固体废物的增加，阿拉伯联合酋长国（阿联酋）拉斯海玛（RAK）的官员正在评估这些材料的再利用，而不是将其倾倒在垃圾填埋场中。此外，由于夏季交通繁忙，交通缓慢以及高温，RAK的沥青路面过早失效。为了帮助解决这些问题，本研究旨在研究将废塑料纤维添加到热拌沥青（HMA）中的效果。在具有两种沥青粘合剂等级和两种废塑料纤维含量（混合重量的0.5％和1％）的标准HMA上进行测试。结果显示，通过添加废塑料纤维，在-10和21.1°C温度下的HMA抗断裂性和在54.4°C温度下的抗车辙性提高。为了全面改善沥青路面的性能，发现最佳废塑料纤维含量为混合物重量的0.5％。因此，通过将废塑料纤维添加到HMA中，可以通过重复使用废弃的塑料废料来实现沥青路面性能的改善（抗车辙和龟裂性）以及对环境的积极影响。
