摘　　要：水泥稳定碎石是高等级公路最常用的基层结构类型,水泥作为水泥稳定碎石的胶结料,对混合料强度有重要影响。通过室内采用不同标号的水泥进行水稳碎石混合料强度试验,结果表明,同等水泥剂量条件下,水泥标号对水稳混合料强度有显著影响,水泥标号越高,水稳碎石混合料早期强度越高。Cement-stabilized crushed stone is currently the most commonly used type of base structure of high-grade highways in China. As cement-stabilized crushed stone binder, cement has a crucial impact on the strength of the mixture. In this paper, the strength test of water-stabilized crushed stone mixture is carried out indoors with different grades of cement. The results show that under the same cement dosage, the cement grade has a significant effect on the strength of the water-stabilized mixture. The higher the cement grade is, the higher early strength of stone mixture is.
