摘　　要：研究了高黏改性乳化沥青的配方技术和生产工艺,考察了乳化荆的种类和SBS改性的掺量对改性沥青及改性乳化沥青蒸发残留物性能的影响。通过黏结性能测试表明,当SBS改性剂的掺量达到3.5%,采用进口的JS-1乳化剂,制备得到的改性乳化沥青满足高黏改性乳化沥青的指标要求,且具有较高黏结强度,能够满足超薄磨耗层的应用要求。Research had been done to study ingredient design and preparation process of high - viscosity modified emulsified asphalt, and the influence of content of SBS and kind of emulsifier on performance of resi- due after evaporation of modified emulsified asphalt was found out. The bond performance test showed that when content of SBS modifier was 3.5% and the imported emulsifier JS - 1 was used, the prepared modified emulsified asphalt could meet the index requirement of high - viscosity modified emulsified asphalt. It had high - viscosity performance and met the application request of NovaChip.
