The concept of sustainability is considered essential in the development of the asphalt mixtures industry, due to its economic and environmental benefits. This study attempts to highlight the potential benefits of sustainability using Reclaimed Asphalt Pavement (RAP). It reviews previous studies conducted on RAP to obtain the most important characteristics in how to use the optimal content of RAP and its effect on some basic properties such as resilient modulus, susceptibility to moisture, permanent deformation, and fatigue. This study mainly focuses on the advantages of using RAP materials in hot mix asphalt (HMA). The results indicated that adding 30% of RAP to virgin asphalt mixtures gives the best performance in terms of the most studied characteristics.

由于其经济和环境效益，可持续性的概念在沥青混合料行业的发展中被认为是必不可少的。本研究试图强调使用再生沥青路面 (RAP) 的可持续性的潜在好处。它回顾了以前对 RAP 进行的研究，以获得关于如何使用 RAP 的最佳含量及其对一些基本特性（如弹性模量、潮湿敏感性、永久变形和疲劳）的影响的最重要特征。本研究主要关注在热拌沥青混合料 (HMA) 中使用 RAP 材料的优势。结果表明，在研究最多的特性方面，将 30% 的 RAP 添加到原始沥青混合料中可获得最佳性能。
