Abstract： in recent years, China' s highway construction has a rapid development, has initially formed a power connection, highway network extending in all directions, so the focus of the future will be from new road construction to old road maintenance and road maintenance tasks will be increasingly burdensome. Str eng then highway mai nt enance t echnology research and application, and will continue to improve the level of highway maintenance, and quality, effectively
ext ending the service life of the road. In foreign
countries, the micro table place technology has been
widely used in highway maintenance, and proved to be a highly cost—effective maintenance measures. Slurry seal in China has been gradually used in highway highway and rural highway maintenance. Emulsified bitumen slurry seal is mainly introduced in this paper the characteristics and construction technology, and discusses its application in highway maintenance.
