微表处用SBS改性沥青乳化剂技术研究

Technical Research on SBS Modified Asphalt Emulsifier Used for Micro-Surfacing

主要介绍了SBS改性微表处技术,针对SBS改性沥青高黏度、难乳化的特点,通过对乳化剂的性能研究,提高其乳化能力,达到对SBS改性沥青较好的乳化效果,并对比SBR改性微表处测试了其乳化沥青及沥青混合料的技术指标,结果表明:SBS改性微表处可以达到SBR改性微表处的应用效果,并在有些指标上优于SBR改性微表处,并且SBS改性微表处在经济效益上具有较大优势。

This paper described the SBS modified micro -surfacing technology, SBS modified asphalt has the characteristics of high viscosity and difficult to emulsify. Through the study on the performance of e- mulsifier, the emulsification ability was enhanced, the SBS modified asphalt could achieve better emulsifica- tion effect, and comparing to the SBR modified micro - surfacing, the technical index of emulsified asphalt and asphalt mixture were test. The results showed that SBS modified micro - surfacing could achieve the appli- cation effect of SBR modified micro - surfacing , it preceded SBR modified micro - surfacing on some target and had more supeliority on the economic benefits.
