弯沉预估控制法用于半刚性基层施工质量控制的试验研究

Laboratorial Study on Deflection Forecasting Control Method for Controlling Construction Quality of Semi-Rigid Bases

在试验研究和对试验路面各结构层不同龄期的表面弯沉进行跟踪测定的基础上 ,应用概率统计与非线性回归的方法 ,对不同材料、不同剂量的半刚性基层表面弯沉及其回弹模量随龄期的变化规律进行了研究分析 ,得到了若干重要结论及统计回归公式 ,并由此提出了实时监控半刚性基层施工质量的弯沉预估控制方法。

On the basis of measuring the deflection of cement and lime stabilized gravel bases in different ages and laboratorial study, this paper analyses the surface deflection of cement and lime stabilized gravel base and the change regulations of modulus following the ages, and draws some important conclusions and presents corresponding regression formulas. According to the conclusions, a deflection forecasting control method for controlling construction quality of semi rigid bases is presented.
