乳化改性沥青是继改性沥青之后的又一种新型沥青路面结合料,应用范围宽,性能优良,特别是结合稀浆封层新技术对路面进行微表处理,用以消除路面的开裂、光滑、车辙、松散、老化等病害,提高路面平整、耐磨、防滑、防水等性能,具有施工速度快、路面质量好、燃料省、沥青用量少、工程造价低、减少环境污染、降低劳动强度、延长施工季节等特点。因此,在发达国家中获得了迅速的推广应用。我国由于大规模的高等级公路建设起步较晚,对于乳化改性沥青生产的装备,助剂等一系列有关应用技术的研究也相对滞后。但是,随着高等级路面逐步进入维修期,乳化改性沥青在国内必将展现出广阔的应用前 Emulsified modified asphalt is another new type of asphalt pavement binder after modified asphalt. It has a wide range of application and excellent performance. Especially, it combines the new technology of slurry seal with micro-surface treatment to eliminate the cracking of pavement, Smooth, rutting, loose, aging and other diseases, improve road surface roughness, wear-resistant, non-slip, waterproof and other properties, with the construction speed, good road quality, fuel province, asphalt dosage less, low construction cost, reduce environmental pollution and reduce labor Strength, to extend the construction season and other characteristics. Therefore, it has been rapidly popularized and applied in developed countries. In our country, due to the late start of large-scale high-grade highway construction, the research on a series of related application technologies such as the equipment and additives for emulsion modified bitumen is relatively lagging behind. However, with the gradual entry of high-grade pavement into the maintenance period, emulsified modified asphalt will surely show a broad application in China
