郑西客运专线路基基床表层级配碎石施工技术

Construction Technology of Graded Crushed Stone on Subgrade Bed Surface in Zhengzhou-Xi＇an Passenger Dedicated Line

郑西客运专线无砟轨道路基基床表层采用0．4m厚级配碎石填筑。文中对ZXZQ01标段级配碎石的施工技术及试验检测作了总结、探讨认为：严按标准压实，遵守工艺流程，控制施工要点，认真抽检，就能保证施工质量。该段竣工抽检，各项指标的合格率均达到100％。

Ballastless track subgrade surface of Zhengzhou-Xi＇an Passenger Dedicated Line is filled with 0.4m graded gravels. This paper summarizes and explores the construction technology and detection test of graded crushed stone in ZXZQ01 bid section. It is considered that standard compaction, strict process flow, construction point control and careful sampling inspection may ensure construction quality. During sampling inspection of this section, the pass rate of each indicator reaches 100%.
