高速公路水泥混凝土精铣刨处治研究

Research on Fine Milling of Expressway Cement Concrete

为研究精铣刨施工在水泥混凝土路面处治中的应用效果,文章结合桂林绕城高速公路精铣刨处治施工项目,通过分析精铣刨施工的铣刨机理,确定铣刨刀间距与铣刨纹理深度的关系,从铣刨速度、铣刨深度以及铣刨过渡段控制等环节研究精铣刨施工工艺流程,总结了用平整度指标和抗滑性能指标评价精铣刨施工效果的要求与方法。

In order to study the application effect of fine milling construction in the treatment of cement concrete pavement,by combining the fine milling treatment construction project of Guilin Ring Expressway,this article analyzes the milling mechanism of fine milling construction,determines the relationship between the spacing of milling cutter and the milling texture depth,studies the fine milling construction process from milling speed,milling depth and milling transition section control,and summarizes the requirements and methods for using the flatness index and anti-sliding performance index to evaluate the fine milling construction effect.
