基于过程能力指标的水稳基层3D数字摊铺技术质量控制研究

Research on Quality Control of 3D Digital Paving Technology Based on Process Capability Index for Water Stable Base of Ligao Expressway

溧高高速公路水泥稳定碎石基层3D数字摊铺技术是江苏省高速公路水稳摊铺中首次采用的摊铺工艺,本研究采用六西格玛管理中过程能力指数和过程性能指数的分析方法,对3D数字摊铺工艺和传统的基准线法摊铺工艺的过程能力进行了分析比较,研究结果表明:3D数字摊铺工艺利用光学技术、电子技术和自动控制技术,对摊铺机进行控制的结果有效,在高程控制、横坡度控制、平整度控制及摊铺厚度控制等方面都优于基准线法,可以推广使用。

The 3D digital paving technology for the cement stabilized macadam base of Ligao expressway is the first paving technology used in the water stable paving of Jiangsu Expressway.The process capability index and process performance index of Six Sigma management are used to analyze and compare the process capability of 3D digital paving technology and traditional baseline paving technology,and the study show that:3D digital paving technology using optical technology,electronic technology and automatic control technology,can effectively control the paver,and is superior to the baseline method in elevation control,cross slope control,flatness control and paving thickness control,which can be widely used.
