1 纤维在SMA混合料中的作用沥青玛蹄脂碎石(StoneMasticAsphalt,简称SMA)是一种新型的沥青路面材料,与普通沥青混凝土不同,它是以粗集料构成空间骨架,而由沥青、矿粉和纤维组成的玛蹄脂填充骨架的空隙,形成密实结构的沥青混合料。SMA路面突出的优点在于:(1)粗集料形成的骨架结
The role of fiber in the SMA mixture StoneMasticAsphalt (StoneMasticAsphalt, referred to as SMA) is a new type of asphalt pavement material, and ordinary asphalt concrete is different, it is coarse aggregate to form a space skeleton, and asphalt, Mastic powder composed of mineral powder and fiber fills the interstices of the skeleton to form a compact structure of asphalt mixture. SMA pavement prominent advantages are: (1) the formation of coarse aggregates skeleton
