摘　　要：沥青混合料是一种比较复杂的复合型材料,它的力学性能与矿料的组成直接相关。介绍了骨架密实型、骨架空隙型和悬浮密实型等3种矿料级配类型的结构特点和工程特性。结合通化市的实际工程经验,指出采用骨架密实型的沥青混合料矿料级配比较理想。在沥青混合料配合比设计中,还应考虑关键性筛孔和最大公称尺寸的影响。Asphalt mixture is a kind of complicated composite materials,which mechanical property is related with mineral aggregate composition.There are three kinds of mineral aggregate gradation,skeleton dense structure,skeleton void structure and floating dense structure introduced in this paper on their separate structure feature and engineering characteristics.Combined with practical experience in Tonghua,it may be more ideal to use the asphalt mixture mineral aggregate gradation with skeleton dense structure.Moreover,the influences of key mesh and the biggest nominal size for asphalt mixture mix design should be considered.
