对公路路基施工压实度异常问题的探讨对公路路基施工压实度异常问题的探讨 中图分类号; U416.1 文献标识码:A 文章编号: 摘要:在道路施工过程中,不管是路基添筑、路堑挖方、基层摊铺,还是沥青面层施工,压实度控制与检测是质量控制的关键环节之一,也是最重要的检测指标之一。如何科学地检测压实度,准确地评定施工压实质量也就非常重要。然而,压实度检测过程中常出现几种异常情况,使得质量人员、监理人员难以对检测结果进行评定,不仅影响了工程施工进度,而且若出现错误的评判结论,将给承包商造成无法挽回的经济损失。为此,结合各种施工现场实际情况,就压实度检测过程中出现的异常进行分析,进而提出解决处理的方法。 关键词:路基;压实度;异常;问题 Abstract: in the road construction process, whether embankment construction, highway excavation, add the paving, or construction of asphalt layer, compaction degree control and detection is the key link of quality control, and also one of the most important testing indexes. How to scientific detection compaction degree, to accurately assess construction compaction quality also is very important. However, the compaction test process middling several abnormalities, make quality personnel and supervisor is difficult to assess the detection results, not only affects the engineering construction progress, and if the error evaluation conclusion, will give the contractor cause irreparable economic loss. Therefore, the construction of the actual situation, the compaction test appeared in the process of abnormal analysis, and put forward the method of handle.
