China has an extremely rich natural sand stone, but more for the sub-base and grassroots. To make full use of local materials to reduce the project investment, speed up road construction, this large size cement stabilized gravel on the applications studied. This will determine the maximum particle size mixture is 80mm. In the research, theoretical analysis and experimental, based on the principle of maximum density gradation control for the guidance, respectively, indoor particle screening, compaction test, test and mixture ratio of unconfined compressive strength, shear strength, frost resistance, crack resistance, shrinkage, etc. Study. Explore the large size of the water stabilized gravel road base as quality control indicators and control standards and new facilities construction process steps. Through the technical and economic analysis showed that the large size of cement stabilized sand and gravel can be used as the secondary build high quality road base, and lower cost, has good application prospects.
