The durability of asphalt pavements is crucial for sustainable road infrastructures. This systematic review compares the Marshall and Superpave asphalt mix design protocols, with a particular focus on the integration of polymer-modified bitumen (PMB) and rejuvenators. Although the Marshall method remains widely used for its simplicity and cost-efficiency, its empirical basis limits its effectiveness to meet modern pavement performance demands. In contrast, the Superpave system offers improved resistance to rutting, longer fatigue life, and better mitigation of moisture damage. The review traces the evolution of asphalt mix design, identifies current challenges, and emphasizes the need for transitioning toward performance-based frameworks. Special attention is given to the incorporation of polymers such as Styrene-Butadiene-Styrene (SBS), Styrene-Butadiene-Rubber (SBR), and Polyethylene (PE), which significantly enhance the mechanical properties of asphalt mixtures. The role of rejuvenators in restoring aged binders and enabling pavement recycling is also examined. Finally, the manuscript provides strategic recommendations for adopting Superpave to enhance pavement durability and reduce lifecycle maintenance costs. Overall, this comprehensive review advances knowledge on asphalt mix design, fostering innovation and sustainability while promoting long-term resilience in road pavement infrastructures.
沥青路面的耐久性对于可持续道路基础设施至关重要。本系统综述比较了马歇尔和超级路面沥青混合料设计方案，特别关注聚合物改性沥青（PMB）和再生剂的整合。尽管马歇尔方法因其简单性和成本效益仍被广泛使用，但其经验基础限制了其满足现代路面性能要求的有效性。相比之下，超级路面系统具有更好的抗车辙性能、更长的疲劳寿命以及更好的水分损害缓解能力。该综述追溯了沥青混合料设计的演变，识别了当前的挑战，并强调了向基于性能的框架转变的必要性。特别关注了苯乙烯-丁二烯-苯乙烯（SBS）、苯乙烯-丁二烯橡胶（SBR）和聚乙烯（PE）等聚合物的掺入，这些聚合物显著增强了沥青混合料的力学性能。还研究了再生剂在恢复老化粘结料和实现路面再生方面的作用。最后，本文稿为采用超级路面以提高路面耐久性和降低生命周期维护成本提供了战略建议。总体而言，这一全面综述推进了关于沥青混合料设计的知识，在促进道路路面基础设施的长期恢复力的同时，推动了创新和可持续性。
