| 摘 要： | 为了对改性乳化沥青高温性能及影响因素进行更好地评价,选用直接加热蒸发法获取SBR及SBS改性乳化沥青残留物。在此基础上,进行多应力重复蠕变恢复试验,探讨温度、胶乳含量及胶乳种类3个因素对改性乳化沥青高温性能的影响。研究结果表明,随着温度的升高,SBR改性乳化沥青残留物高温抗变形能力变弱;随着胶乳含量的增加,SBR改性乳化沥青残留物高温抗变形能力变强;SBS改性乳化沥青高温性能优于SBR改性乳化沥青。

| Abstract: | In order to evaluate the high temperature performance and influence factors of modified emulsified asphalt, this paper obtains residues from SBR/SBS modified emulsified asphalt by direct thermal evaporation method, and then carries out the MSCR test to study the influence of temperature, latex content and latex type on the high temperature performance of modified emulsified asphalt. The data shows that rutting resistance of SBR modified emulsion residue under high temperature decreases with temperatures going up, and increases with latex content increasing. It finds out that the high temperature performance of SBS modified emulsion residue is better than that of SBR modified emulsion. |
