Study On Materials Composition Design Method And Performance Variation Of Skeleton-pore Cement Stabilized Aggregate Base

Skeleton-pore Cement Stabilized Aggregate base can be quickly ruled out the water within the structure of the road, it can improve performance by reducing the damage of water on the pavement structure and increase the life of pavement. The performance of permeable base is directly to the life of pavement, the study on materials composition design method and performance variation of Skeleton-pore Cement Stabilized Aggregate base is important.The paper present Materials Design of Skeleton-pore Cement Stabilized Aggregate base, mechanical properties, water properties, frost resistance and fatigue properties. First of all, it studies the material design methods from the material composition design specifications, material gradation theory, mixture forming methods and Mixed agents; secondly, it studies the void and coefficient permeability of the Skeleton-pore Cement Stabilized Aggregate; also studies the relationship and factors between the void and coefficient permeability. Finally, it studies the mechanical properties, frost resistance and fatigue properties of the Skeleton-pore Cement Stabilized Aggregate; also obtains intensity variation, variation of antifreeze, fatigue life diagram with different doses of cement, different SBR latex content and different fly ash content. It analyzes the reasons from cement content, polymer cement ratio, powder cement ratio.By studying on materials composition design method and performance variation of Skeleton-pore Cement Stabilized Aggregate base, we present the design of appropriate materials and got mixed with agents for improving the frost resistance and fatigue properties of the Skeleton-pore Cement Stabilized Aggregate is of great significance and analysis of the cement mixed with doses of change and agents on the drainage properties of mixtures.
