摘要
目前通常采用挖坑取样法检测路基水稳层压实质量,不仅破坏路面整体结构,干扰后续施工作业,而且用有限个试坑样本反映整幅路段压实质量,存在一定偏差。研制开发了公路水稳层振动碾压质量实时监控系统,建立了压实质量实时监测指标(Compaction Value,CV)与水稳层压实度之间的质量评估模型,提出了水稳层全工作面压实质量快速评估方法,可分析压实均匀性和判断碾压薄弱区域,实现了100%施工区域水稳层压实质量的实时监控与反馈控制,为确保高等级公路水稳层施工质量提供了新的技术手段。
The commonly-used inspection method of water stable layer compaction quality relies on spot sampling tests at current time. However,this method not only damages the pavement structure and interferes with subsequent construction operations,but also has a certain deviation,because of using the limited test pit samples to show the compaction quality of the whole road. Therefore,a real-time monitoring system for vibration compaction quality of highway water stable layer was developed,and a quality assessment model between the real-time monitoring compaction values（ CV） and the compactness of water stable layer was established. Then,a fast compaction quality assessment method of water stable layer was proposed to analyze the compaction uniformity and judge the weak area of compaction. The proposed method realizes the real-time monitoring and feedback control of the water stable layer compaction quality with 100% coverage of construction zone,and provides a new technical measure to ensure the construction quality of highway water stable layer.
