有机改性活性矿物(Activated Mineral Binder Stabilizer,简称AMBS)是一种新型的沥青改性材料,由磷酸盐矿的工业副产品改性形成。该文通过理论分析和室内试验,在有机活性矿物改性机理的基础上,研究掺加AMBS对SMA混合料性能的影响。研究结果表明:有机活性矿物可以显著提高SMA混合料的高温性能与抗疲劳性能,抗水损害性能略有降低,但可以满足规范要求,且掺量15%的有机活性矿物SMA沥青混合料性能最优。 Activated Mineral Binder Stabilizer (AMBS) is a new type of bitumen-modified material formed by the modification of industrial byproducts of phosphate ore. In this paper, the theoretical analysis and laboratory tests were carried out to study the effect of AMBS on the properties of SMA mixtures based on the modification mechanism of organic active minerals. The results show that: the organic active minerals can significantly improve the high temperature performance and fatigue resistance of SMA mixture, water resistance damage slightly reduced, but can meet the regulatory requirements, and the amount of 15% organic active mineral SMA asphalt mixture performance excellent.
