摘要：利用废轮胎胶粉作为沥青改性剂,采用降粘预处理工艺制备了废胶粉改性乳化沥青。实验对比了4种乳化剂对基质沥青乳化效果,考察了乳化时间、乳化剂用量、增稠剂用量、稳定剂用量和FCC油浆添加量对废胶粉改性乳化沥青性能的影响,并利用光学显微镜分析了其微观结构。实验结果表明,乳化剂B与基质沥青的配伍性最好,在乳化时间为15 min,乳化剂用量为1.5%,增稠剂用量为0.5%,稳定剂用量为0.5%,FCC油浆用量为3%,SBR胶乳添加量1%时,制备得到废胶粉改性乳化沥青基本能满足我国乳化沥青大部分用途的标准要求。
Crumb rubber was used as asphalt modifier and Crumb Rubber Modified Asphalt（ CRMA） emulsion was prepared by using reducing viscosity pretreatment process. The emulsifying effect was compared by four kinds of emulsifiers for asphalt,and the factors affecting the treatment were studied. The results show that the emulsifier B is much more compatibility with asphalt than others. Under the best condition of emulsifying time 15 min,emulsifier mass fraction 1. 5%,thickener mass fraction 0. 5%,stabilizer mass fraction 0. 5%,FCC slurry oil mass fraction of CRMA 3%,SBR latex mass fraction 1%,CRMA emulsion can basically meet the standard requirements of asphalt emulsion most purposes.
