Abstract:The requirements for technical indices for content of fine sand, such as the strength of mixture, frost resistance, and resilient modulus were examined by using the sand in the area of Inner Mongolia to take the place of fine aggregates to make up the cement stabilized gravel mixtures. The results have shown that the road performance of mixture can meet the requirements in specifications when the sand content is 10% , and it can be used for base course in high -class highways and will have some economic benefits.
Keywords:cement stabilized crushed stone  base course  fine sand  performance
