以集料的体积指标作为级配设计的基本参数,粗集料形成的骨架嵌挤结构为出发点,通过振动击实确定每档粒径集料的体积指标,并以该指标为基本控制参数,混合料设计空隙率为已知控制变量,同时引入Bailey设计方法中粗集料比(CA)用以控制混合料的离析,建立集料体积指标的关系表达式。得出骨架孔隙结构水泥稳定碎石的级配范围和设计级配。根据室内试验和理论分析得出多空隙水泥稳定碎石的含水量的确定方法。通过旋转压实和静压成型试件,分析并提出适宜的压实方案。建立压实次数和7 d抗压强度的关系。 Taking the volume index of aggregate as the basic parameter of grading design and the skeleton embedded structure formed by coarse aggregate as the starting point, the volume index of each particle size aggregate was determined by vibration compaction. Taking the index as the basic control parameter, The void ratio of the mixture design is a known control variable. Meanwhile, the coarse aggregate ratio (CA) in the Bailey design method is introduced to control the segregation of the mixture, and the relation expression of aggregate volume index is established. The grading range and design grade of the cement stabilized macadam are obtained. Based on the laboratory test and theoretical analysis, the method for determining the water content of multi-void cement stabilized macadam was obtained. By rotating compaction and hydrostatic forming specimens, analysis and propose a suitable compaction program. Establishing the relationship between the number of compaction and the compressive strength at 7 d.
