摘　　要：稀浆封层用的乳化沥青为慢裂型乳化沥青,普通阳离子乳化沥青多为中裂或者快裂型,非离子乳化沥青主要为慢裂。把两种沥青乳化剂进行复配,结合两种乳化沥青的优点制备复配型乳化沥青。主要总结阳离子沥青乳化剂与不同种类非离子沥青乳化剂的复配,并进行乳化沥青的性能测试,是否适用于稀浆封层。The emulsified asphalt used for slurry seal is a slow-cracking one.The common cationic emulsified asphalts are usually of medium cracking of fast cracking types.The nonionic emulsified asphalt is mainly slow cracking type.Two asphalt emulsifiers are compounded.Combined with the advantages of two emulsified asphalts,the compound emulsified asphalt is prepared.The compounding of cationic asphalt emulsifier and the different nonionic asphalt emulsifiers is mainly summarized.The performance experiment of emulsified asphalt is carried out for whether or not suitable for the slurry seal.
