Asphalt fine aggregate matrix (FAM) consists of a binder, fine aggregate, filler, and air voids. Studies on FAM, which is one scale smaller than asphalt concrete (AC), have been gaining attention among researchers because of its considerable similarities with AC and increased testing efficiency it provides. FAM tests are mostly performed to evaluate relative material performance in case of damage. This review presents recent studies regarding mix design, fabrication methods, material incorporation, and experimental design to evaluate the performance of FAM mixtures. This study also summarizes the recent research findings on using micromechanical computational modeling and the correlation between the FAM and AC properties. It is the general consensus that microstructure of the FAM has a substantial effect on the mechanical properties and evolution of damage in AC. The main issue in the available literature is the detailed understanding of how FAM exists in the AC and how to replicate this for experimental purposes. This lack of understanding makes it to view the literature as disorganized information because each researcher employs his own method to study FAM materials. Therefore, there is a need to establish comprehensive fabrication and testing protocols as a specification to precisely resemble the FAM that exists within AC and hence accurately predict the performance characteristics of AC.

沥青细骨料基质（FAM）由粘合剂，细骨料，填料和空隙组成。FAM的研究规模比沥青混凝土（AC）小一倍，由于它与AC的相似之处以及所提供的更高的测试效率而受到了研究人员的关注。FAM测试主要用于评估损坏情况下的相对材料性能。这篇综述介绍了有关混合物设计，制造方法，材料掺入和用于评估FAM混合物性能的实验设计的最新研究。这项研究还总结了使用微机械计算模型以及FAM和AC特性之间的相关性的最新研究成果。公认的共识是，FAM的微观结构对AC的机械性能和损伤演变有重大影响。现有文献中的主要问题是对AC中FAM如何存在以及如何将其复制用于实验目的的详细理解。由于缺乏了解，因此将文献视为杂乱无章的信息，因为每个研究人员都采用自己的方法来研究FAM材料。因此，需要建立全面的制造和测试协议作为规范，以精确地类似于AC中存在的FAM，从而准确地预测AC的性能特征。由于缺乏了解，因此将文献视为杂乱无章的信息，因为每个研究人员都采用自己的方法来研究FAM材料。因此，需要建立全面的制造和测试协议作为规范，以精确地类似于AC中存在的FAM，从而准确地预测AC的性能特征。由于缺乏了解，因此将文献视为杂乱无章的信息，因为每个研究人员都采用自己的方法来研究FAM材料。因此，需要建立全面的制造和测试协议作为规范，以精确地类似于AC中存在的FAM，从而准确地预测AC的性能特征。
