1 前言 六十年代末,少数发达国家在公路上开始应用乳化沥青稀浆封层技术,以达到保护、改善路面的目的。由于乳化沥青稀浆封层技术与其它施工技术相比,具有施工速度快、施工质量好、制约因素少、经济效益显著、工艺简单、便于推广等明显优势。所以,该技术近年来发展很快。现在,乳化沥青稀浆封层技术已广泛应用于公路路面的新建工程、旧路改造工程及日常养护工作,用以提高路面的防水、抗滑、耐磨、平整等性能,使路面的磨损、老化、裂缝、坑槽等病
1 Preface In the late 1960s, a few developed countries started to apply emulsified asphalt slurry sealing technology on the roads in order to achieve the goal of protecting and improving roads. As emulsified asphalt slurry seal technology compared with other construction techniques, with the construction speed, good construction quality, fewer constraints, significant economic benefits, process is simple, easy to promote and other obvious advantages. Therefore, the technology has developed rapidly in recent years. Now, emulsified asphalt slurry seal technology has been widely used in road construction of new roads, old road reconstruction projects and routine maintenance work to improve the pavement waterproofing, anti-skidding, wear-resistant, flat and other performance, the road wear, Aging, cracks, pit and other diseases
