摘　　要：高等级公路路面基层大多采用水泥稳定土基层 ,厚度大于 30 cm ,按照规范要求应进行分层铺筑。通过改进施工设备、优化施工工艺 ,1层铺筑较分层铺筑节约了施工成本 ,提高了施工工效 ,大大改善了基层的整体强度 ,具有很大的推广运用价值。For the base course of high-type highway surfaces the cement stabilized soil base course is used to be adopted that is spred by layers in case of its thickness greater than 30 cm in accordance with the Specifications. But the one-course spreading method may save cost,enhance work efficiency and result in quite greater integrated strength of base in comparison to the spreading way by layers, if the construction equipments are improved and technology optimized. So it is worthy to be popularized.
