Abstract: At present the most prominent problem of emulsified asphalt slurry seal technology was the lack of slow breaking and fast setting asphalt emulsifier. Amide cationic asphalt emulsifier was synthesized using octadecanoic acid, seed oil fatty acids and triethylene tetramine as raw materials. The best conditions were obtained. Comparing the test results of the performance and the road construction of emulsified asphalt, it was found that the amide cationic asphalt emulsifier had advantages of strong emulsifying capacity, less emulsifier dosage, higher adhesion speed and better storage stability.

摘要： 我国乳化沥青稀浆封层技术比较突出的难题是缺少慢裂快凝快通车型沥青乳化剂。实验采用硬脂 酸、 瓜子油脂肪酸和三乙烯四胺合成制备混合酰胺型阳离子沥青乳化剂, 确定了最佳工艺条件。通过乳化沥青性能 测试及路用施工, 该乳化剂具有乳化能力强、 乳化剂用量相对少、 附着速度快、 储存稳定性好等优点。
