【摘要】 水泥乳化沥青(CA)砂浆广泛应用于高速铁路建设中,作为CA砂浆的主要成分,乳化沥青对CA砂浆的性能有重要影响。从基质沥青、乳化剂、外加剂、制备工艺四个方面对CA砂浆专用乳化沥青性能的影响进行了综合评述,分析表明:乳化剂是影响乳化沥青性能的关键因素,乳化工艺中各种参数(如温度、乳化时间、胶体磨间隙等)对乳化沥青性能也有重要影响。更多还原

【Abstract】 CA mortar is widely used in high-speed railway construction.As one of the important components of CA mortar,emulsified asphalt has important influence on the performance of CA mortar.The effect of the four factors,namely,base asphalt, emulsifier,admixture and preparation technology,on the performance of CA mortar special-purpose emulsified asphalt is reviewed.The analysis shows that emulsifier is the key factor.Various parameters(e.g.,temperature,emulsifying time and colloid mill gap) of emulsification technology also has important influence on performance of emulsified asphalt.更多还原
