The skeleton pore structure of cement stabilized macadam base can penetrate the pavement structure within the water quickly ruled out the road to reduce water damage to the pavement structure to improve road performance and improve the life of the pavement . The drainage base performance is directly related to the road performance the skeleton pore structure of cement stabilized macadam base material composition design methods and performance variation so the research is of great significance . This paper studies the the skeleton pore structure of cement stabilized gravel composed of design methods , mechanical properties , drainage performance , frost resistance and fatigue properties . Starting material design indicators , the material gradation theory , mixes molding methods , Mixed agent four aspects of materials design method . Followed by different cement dose different SBR emulsion ash , fly ash the skeleton pore structure of cement stabilized macadam porosity and permeability coefficient , and to study the relationship between the two and the influencing factors . Of the skeleton pore structure and mechanical properties of cement stabilized crushed stone , frost resistance , fatigue performance research , come to different cement dose different SBR emulsion dosage the skeleton pore structure of fly ash cement stabilized gravel the variation of intensity variation , frost resistance , fatigue life, and from cement dose , poly gray than pink gray than three analysis of the reasons for the regular . Design methods and performance study of the variation of the skeleton pore structure of cement stabilized macadam base material , the proposed appropriate materials design method , cement dose changes and admixture drainage performance of the mixture , the outer admixture is of great significance for improving the the skeleton pore structure of cement stabilized gravel antifreeze properties and fatigue performance .
