摘要/Abstract

摘要： 采用线型SBS胶乳制备一种SBS改性乳化沥青，并对乳化沥青性能进行分析。实验考察了乳化剂种类、乳化剂质量分数，线型SBS胶乳质量分数以及制备工艺对改性乳化沥青性能的影响，利用扫描电镜观察了乳化沥青的形貌。结果表明，当乳化剂为OP⁃10、乳化剂质量分数为2.0%、线型SBS胶乳质量分数为4.0%、剪切速率为3 000~4 000 r/min、剪切时间为30 min时，制备的线型SBS胶乳改性乳化沥青蒸发残留量为65.5%、储存稳定性分别为0.43%（1 d）和2.15%（5 d）、针入度为65 mm、软化点为55.7 ℃，符合道路改性乳化沥青的技术要求，SBS在乳化沥青中分散均匀。

Abstract: A SBS modified emulsified asphalt was prepared by using linear SBS latex, and the performance of emulsified asphalt was analyzed. Experiments set to test how emulsifier types, amounts of emulsifier, usage of line⁃type SBS latex and preparation technology affect the performance of modified asphalt emulsion. The morphology of modified asphalt emulsion has also been studies by using scanning electron microscope. The experiment results showed that when emulsifier was OP⁃10, usage of emulsifier was 2.0%, amount of line⁃type SBS latex was 4.0%, the shearing rate was 3 000~4 000 r/min, the shearing time was 30 min, the evaporation residue of modified asphalt emulsion was 65.5%, storage stability was 0.43% (1 d) and 2.15%(5 d), penetration was 65 mm and the softening point was 55.7 ℃, which matches the technical requirements of the road modified emulsified asphalt. SBS is also dispersed uniformly in emulsified asphalt.
