SBS改性乳化沥青的研究及应用进展

Study and Application Progress of SBS Modified Emulsified Asphalt

SBS改性乳化沥青具有较好的高低温性能,是目前道路维修养护领域发展前景较好的高技术产品,但由于SBS改性乳化沥青乳化难度高,且制备的产品易破乳,所以SBS改性乳化沥青仍是乳化沥青领域较难大规模推广的技术。介绍了SBS改性乳化沥青制备的工艺流程,对比了3种制备工艺的优缺点。并重点介绍了三种工艺制备SBS改性乳化沥青的研究及应用进展。

SBS modified emulsified asphalt has good high-low temperature properties, and is a promising product in the road maintenance field. But SBS modified emulsified asphalt is difficultly emulsified, and the demulsification phenomenon of SBS modified emulsified asphalt product easy appears. In this paper, the process flow of preparing SBS modified emulsified asphalt was described, The advantages and disadvantages of three techniques of preparing SBS modified emulsified asphalt were compared. The research and application progress of SBS modified emulsified asphalt were introduced.
