浅谈公路SMA路面质量控制

Quality Control for SMA Pavement of Highway

SMA系由沥青结合料与少量的纤维稳定剂、细集料以及较多量的填料(矿粉)组成的沥青玛蹄脂,填充于间断级配的粗集料骨架的间隙,组成沥青混合料。SMA路面因其具有良好的抗滑和抗车辙性能被广泛应用于公路的面层。对SMA路面施工质量控制做了简要介绍。

SMA is asphalt mastic composed of asphalt binder,a small amount of fiber stabilizer,fine aggregate and large amount of filler( mineral dust). The asphalt mastic is filled into gaps of gap-graded coarse aggregate skeleton and forms integrated bituminous mixture. SMA pavement is widely used in highway surface due to its good sliding and rutting resistances. SMA pavement construction quality control is briefly described in this paper.
