室内水泥稳定碎石基层试验技术经济指标的研究

利用内蒙古地区的细砂代替细集料配制水泥稳定碎石混合料，研究了室内细砂含量对混合料强度、抗冻性和抗压回弹模量等技术指标的要求，结果表明细砂的掺量为10％时，混合料的路用性能满足规范要求，可用作高等级公路的基层，并具有一定的经济效益。

Study of technical and economic indices for indoor test on cement stabilized gravel base course

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.
