微表处技术在京珠高速公路养护中的应用

The Application of Micro-surfacing in Maintenance of Jing-Zhu Expressway

结合京珠高速公路微表处养护施工的实践,介绍了微表处混合料配合比设计及施工工艺,检测结果显示,微表处对提高路面抗滑性能、平整度和密实度、修复车辙等具有显著效果,改善了路用性能,达到了预防性养护的效果。

Through the micro-surfacing maintenance construction in Jing-Zhu expressway, the mixture proportion design and construction technologies are expounded. The evaluating result shows that the micro-surfacing has great effect on improvements of skidding resistance, smoothness and compactness of the pavement. And micro-surfacing also can repair rutting and improve the function of asphalt pavement surface, which meet the requirement of preventive maintenance.
