摘要
乳化沥青颗粒粒径大小及分布是乳化沥青的一项关键参数,利用乳化沥青颗粒粒度分析仪可方便、准确地观测乳化沥青的颗粒粒径、分布情况及破乳变化过程。选用部分道路石油沥青和乳化剂制备乳化沥青样品,采用乳化沥青颗粒粒度分析仪对乳化沥青的颗粒粒径及分布进行试验分析,并观测乳化沥青的破乳过程,分析乳化沥青颗粒粒径及分布均匀性对乳化沥青的储存稳定性等的影响。
The emulsified asphalt particle size and distribution is a key parameter of emulsified asphalt,particle size analyzer can easily and accurately observe the particle size,distribution and changing process of emulsified asphalt.The emulsified asphalt was prepared by highway asphalt and emulsifier,emulsified asphalt particle size analyzer was used to analyze emulsified asphalt particle size and distribution,The demulsification process of emulsified asphalt was observed,the effect of particle size and distribution uniformity of emulsified asphalt on its storage stability was analyzed.
