一、前言改性稀浆封层作为目前国内高级路面养护的一种最新技术,它是新材料、新工艺和新设备三者的结合,已被公路工程界的专家所关注。有关资料表明,它不仅具有普通稀浆封层的所有优点,而且在填补车辙、治理网裂等病害以及铺筑桥面、隧道、修筑机场,城市道路等特殊环境下的修筑与养护都具有特殊的意义。鉴于改性稀浆封层的诸多优点。我们西安市政工程管理处决定将此项技术引进西安,并向西北地区加以推广。通过大量的室内试验,不但确定出适合于西安地区的改性稀浆封层混合料的最佳配合比,选择了适宜的改性剂、乳化剂等品种及用量,还为改性稀浆封层技术在西安地区大力推广提供了技术依据。
I. Introduction Modified slurry seal as the current domestic advanced pavement maintenance of a new technology, it is a combination of new materials, new technology and new equipment, highway engineering experts have been concerned about. The information shows that it not only has all the advantages of ordinary slurry seal, but also in filling rutting, cracking and other diseases and the management of pavement bridge, tunnels, airport construction, urban roads and other special circumstances of the construction and maintenance of special Meaning. In view of the many advantages of modified slurry seal. We Xi’an Municipal Engineering Management Office decided to introduce this technology in Xi’an, and to promote the northwestern region. Through a large number of indoor tests, not only to determine the best mix of modified slurry seal mixture suitable for Xi’an, select the appropriate modifier, emulsifier and other varieties and dosage, but also for the modified slurry seal Layer technology in Xi’an to promote the technical basis provided.
