摘　　要：分析了改性剂的各种成分(聚合物改性剂、溶胀剂、分散剂、增塑剂及交联剂)对改性沥青性能的影响,选出了最优的沥青性能所对应的改性剂各成分的比例,并提出采用溶剂法制备工艺。该高粘改性剂可直接投入基质沥青(非传统直投入沥青混合料)进行生产改性沥青。该高粘度改性剂不仅能保证改性沥青混合料路用性能,还能有效降低沥青混合料成本,社会经济效益显著。In this paper,the effects of various components of modifier (polymer modifier,swelling agent,dispersant,plasticizer and crosslinking agent) on the properties of modified asphalt were analyzed,to select the asphalt performance corresponding to the components of the modifier . The solvent preparation process was innovatively proposed,And the high viscosity modifier can be directly put into the base asphalt (non-traditional direct into asphalt mixture) to produce modified asphalt. The high viscosity modifier can not only ensure the pavement performance of modified asphalt mixture,but also effectively reduce the cost of asphalt mixture,and has remarkable social and economic benefits.
