20世纪20年代初期,德国用非常精细的骨料、沥青粘接剂和水等组成混合料养护路面,这便是最早的稀浆封层技术。30年代后期,世界各地开始了这方面的研究实验,随着乳化剂和摊铺设备的改进,到了20世纪70年代,出现了改性乳化沥青,稀浆封层技术也开始受到更广泛的重视。随着稀浆封层技术的不断提高和改进,稀浆封层机也迅速成 In the early 1920s, Germany maintained the pavement with a mixture of very fine aggregates, bituminous binders and water - the earliest slurry seal technology. In the late 1930s, research experiments were started in various parts of the world. With the improvement of emulsifiers and paving equipment, by the 1970s, modified emulsified asphalt appeared and slurry sealing technology began to receive more and more attention . As the slurry seal technology continues to improve and improve, slurry seal machine also quickly into
