众所周知,乳化沥青具有易施工不污染环境等优点。一些发达的资本主义国家都使用大量的阳离子型沥青乳液进行修路和养路。各国也相应制订了自己的乳化沥青的标准。某些生产厂家也有自己的分类标准。虽然许多国家的分类及质量要求各不相同,但概括起来有两种分类方法:一种是按乳液的破乳速度分为快裂、中裂、慢裂型三类;一种是按乳液喷洒、贯入或拌合摊铺等不同施工方法分为贯入型和拌合型,并各自提出自己的质量标准。美国的 ASTM2397-79路用
As we all know, emulsified asphalt has the advantages of easy construction does not pollute the environment. Some developed capitalist countries use large amounts of cationic asphalt emulsions for roads and road maintenance. Countries have also formulated their own standards of emulsified asphalt. Some manufacturers also have their own classification criteria. Although classification and quality requirements vary widely in many countries, there are two generalizations of the classification: one is the classification of emulsion breaking speed into three categories: rapid crack, split crack, slow crack type; one is sprayed by emulsion , Penetration or mixing paving and other construction methods are divided into penetration type and mixing type, and each put forward their own quality standards.
