摘要
分别通过外掺法、内掺法和先改性后乳化法制备SBR改性乳化沥青;研究了不同方法制备的SBR改性乳化沥青的多项性能指标,并对三者进行了对比分析。结果表明内掺法得到的改性乳化沥青的综合性能较好,而先改性后乳化法得到的改性乳化沥青抗车辙性能最好。
Three types of SBR modified emulsified asphalt were prepared by different methods that included outward blending,inward blending and emulsifying after modifying method.The multi - performance parameters of SBR modified emulsified asphalt were studied and the three types of preparation methods were comparative analysed.The results showed that the combination properties of SBR modified emulsified asphalt prepared by inward blending method were best,and the anti - rutting property prepared by emulsifying after modifying method was best.
