改性级配碎石基层施工质量控制研究

Study on construction quality control of modified grading gravel base

以某二级公路路面基层改性级配碎石施工现场检测数据为基础,从级配、水泥剂量和压实度三个方面提出对改性级配碎石基层质量的控制措施,得出以4.75 mm以下粒径集料含量作为控制级配变异的关键措施,过9.5 mm方孔筛法能够提高水泥剂量检测精度的结论。

Taking the in-situ detection data of modified grading gravel of the second-level highway pavement base as the basis, the paper puts forward modified grading gravel base quality control measures from three aspects of grading, cement dosage and compaction degree, and concludes the critical measures of taking diameter below 4.75 mm content as the control grading change. In addition, over 9.5 mm square sieving method can improve cement dosage detection accuracy.
