0引言半刚性基层具有良好的板体性,承载能力高,是路面结构的主要承重层,但同时存在抗变形能力差、易出现干缩和温缩裂缝的问题。水泥稳定碎石混合料作为一种良好的半刚性基层修筑材料,目前在中国路面基层施工中被普遍采用,但在施工中普遍存在水泥剂量偏高、易离析、压实困难等问题,造成基层质量隐患。相关研究表明,搅 0 Introduction Semi-rigid base has good board body, high carrying capacity, is the main bearing layer of the pavement structure, but at the same time there is poor resistance to deformation, easy to shrink and shrinkage cracks. As a kind of good semi-rigid base building material, cement stabilized aggregate is widely used in the construction of pavement in China at present. However, there are common problems such as high cement dosage, easy separation and compaction difficulties during construction, Quality problems. Related research shows that stirring
