利用当地的细砂代替细集料配制水泥稳定碎石混合料 ,研究了细砂含量对混合料强度、抗冻性、抗疲劳特性和收缩特性的影响。提出了抗压回弹模量等技术参数 ,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
The effect of fine sand content on the strength, frost resistance, anti-fatigue and shrinkage characteristics of the mixture was studied by using local fine sand instead of fine aggregate to prepare cement stabilized aggregate. The compressive resilience modulus and other technical parameters are presented. The results show that when the content of fine sand is 10%, the road performance of the mixture meets the specifications and can be used as the grassroots of high-grade highways and has some economic benefits
