山区高速公路路面基层施工方法

随着交通荷载的日益增大，路面结构对底基层的施工质量提出了更高的要求。工程实践证明，底基层的施工质量是影响路面使用性能和耐久性能的关键因素之一。结合张承高速张家口段工程施工实践，重点论述了山区高速公路拌和场布置，施工机械设备和材料的配备，施工前准备和施工要点，对于山区高速公路施工具有重要参考价值。

Construction Method of Mountainous Expressway Pavement Base

With the rapid development of traffic load, the requirement to the quality of pavement base con-struction is increasingly strict. Project practice proves that subbase construction quality is one of the criti-cal factors influencing pavement performance and durability. This paper focuses on the mixing field lay-out, the allocation of constructing machinery equipment and material, constructing preparation and the main constructing points of mountainous expressway in combination with the construction practice of Zhangjiakou part of Zhangcheng Expressway, which is of important reference value to mountainous ex-pressway construction.
