摘　　要：不同级配构成对水泥稳定碎石混合料的路用性能有着显著影响。基于工程经验,提出了平衡型骨架密实结构的设计思路,并针对骨架密实级配、悬浮密实级配、平衡骨架密实级配结构进行了水泥稳定碎石混合料配合比优化设计,并进行了路用性能评估。研究结果表明,平衡型骨架密实结构水泥稳定碎石混合料能够有效解决骨架密实级配施工变异性大的问题,避免悬浮密实级配开裂,路用性能表现优异。Different gradation compositions have a significant impact on the pavement performance of cement stabilized gravel mixtures.Based on the engineering experience,the design idea of the balanced skeleton dense structure is put forward,and the optimal mix design of cement stabilized gravel mixture is carried out for the structure of skeleton dense gradation,suspended dense gradation and balanced skeleton dense gradation,and the pavement performance evaluation is carried out.The research results show that,the cement-stabilized gravel mixture with balanced skeleton dense structure can effectively solve the problem of large variability in the construction of skeleton dense gradation,avoid the cracking of suspended dense gradation,and have excellent pavement performance.
