结合韶赣曲江至南雄高速公路中骨架密实型水泥稳定碎石下基层的应用,介绍了骨架密实型水泥稳定碎石基层配合比设计基本思路、方法及步骤;比较了重型击实与振动击实方法对试验结果的影响;对施工工艺要点进行阐述,对完工路段的检测评估表明:骨架密实型水泥稳定碎石基层能提高基层强度、提高抗裂性能。
Combining with the application of the medium-sized and medium-sized cement stabilized macadam subgrade in the Qujiang-Nanxiong Expressway of Shaogan, the basic ideas, methods and steps for the mix proportion design of the compact cement stabilized macadam base were introduced. The compaction and vibration compaction Method on the test results. The main points of the construction process are elaborated. The testing and evaluation of the completed road sections show that the basic structure of the dense cement stabilized macadam base can improve the strength and improve the crack resistance.
