公路工程质量检测中的几点疑难及对策

文章对公路工程质量检测中的稳定材料结合料剂量、混合料配合比及碾压成型材料压实度等检测存在的疑难及解决这些疑难问题的对策进行了探讨。在实际操作中通过建立石灰土剂量-含水量、剂量-龄期工作线、水泥混凝土混合料集料级配检测图和二灰稳定碎石的配合比-压实度工作线,以增强检测数据的真实性,提高检测手段的客观性。

Difficulties in highway engineering quality detection and countermeasures

Some difficulties in the highway engineering quality detection are investigated,such as testing of the binder content in the stabilized material,testing of the proportioning of the mixture,and detection of the degree of compaction of the rolling compacted material,and some countermeasures are put forward based on some practical cases. Through establishing some curves,such as the working curves considering the relationship of lime content and water content and that of lime content and age of lime-soil,the grading detection chart of cement concrete combined aggregate,and the working curve considering the relationship of mixture ratio and degree of compaction of lime and flyash stabilized crushed stone,the authenticity of testing and detection data is strengthened,and the objectiveness of testing and detection measures enhanced.
