摘　　要：优选中国石化生产的聚合物乳液,研究分析了聚合物乳液对乳化沥青和砂浆性能的影响,对聚合物乳液配方进行调整优化,最终开发出可同时改善高铁专用乳化沥青性能和CA砂浆性能的复合改性剂。该复合改性剂与乳化沥青、干粉料相容性较好。与日本P乳剂相比较,既能提高沥青的低温性能,又能提高新拌砂浆的可工作时间和早期强度,同时表现出优异的抗冻性和耐候性。The paper studied effects of polymer emulsion produced by SINOPEC on properties of emulsified asphalt and mortar,and the combined modifier,which could improve properties of special emulsion asphalt for high- speed rail and CA mortar simultaneously,was finally developed. Compatibility of the combined modifier with emulsion asphalt and dry mash was good. The combined modifier with excellent freezing resistance and weather ability could not only improve low temperature properties of the asphalt but also raised workable time and early stage strength of the new stirred mortar comparing with P emulsion agent produced by Japan.
