摘　　要：水泥稳定碎石强度刚度高,整体性好,被广泛应用于公路基层,高寒高海拔地区由于气候环境较为特殊,水泥稳定碎石基层容易产生裂缝病害,骨架密实型的水泥稳定碎石更加适合该地区气候。针对骨架密实结构水泥稳定碎石基层施工,结合高寒高海拔地区的气候特点,分析了各个环节施工可能存在的问题,总结了控制其施工质量的要点,以及查找了一些新的技术和方法以改善这些问题,为改善高海拔地区公路施工质量,延长公路使用寿命提供参考。Cement-stabilized gravel has high strength and stiffness,and good integrity,making it widely used in highway subbases.However,in high-cold and high-altitude areas,the special climatic conditions can lead to cracking and other diseases in cement-stabilized gravel bases.Skeleton-dense cement-stabilized gravel is more suitable for the climate of these regions.This paper focuses on the construction of skeleton-dense structure cement-stabilized gravel bases,analyzing potential problems in various construction stages based on the climatic characteristics of high-cold and high-altitude areas.It summarizes key points for controlling construction quality and identifies new technologies and methods to address these issues,providing references for improving the quality of highway construction in high-altitude areas and extending the service life of the roads.
