Construction method for wide and large-thickness cement stabilized macadam base
The invention discloses a construction method of a wide and large-thickness cement stabilized macadam base. The construction method comprises the following construction steps: S1, preparing the following macadam base raw materials in parts by weight: 100-900 parts of cement, 200-1100 parts of macadam, 100-300 parts of an expanding agent, 20-120 parts of an adhesive and 1000-1600 parts of water; s2, cement, an expanding agent, an adhesive and water are put into a stirring barrel according to the proportion and stirred, and cement paste is prepared; s3, planning design requirements of a base layer; and S4, cleaning the substrate by using a cleaning tool to ensure that the substrate is flat and free of sundries. The adhesive is added into the internal material of the macadam base layer, and the cement layer added with the adhesive is laid at the bottom of the base layer in advance during construction to serve as a foundation for fixation, so that the problems that the lower bearing layer is relatively loose, the surface soil exists, and the bonding compaction effect between the base layer and the lower bearing layer is poor are solved; the quality of the road is improved, the service life of the road is prolonged, and a better use prospect is brought.
本发明公开了一种宽幅大厚度水泥稳定碎石基层施工方法，施工步骤包括：S1、准备如下份数的碎石基层原料：水泥100‑900份、碎石200‑1100份、膨胀剂100‑300份、粘合剂20‑120份与水1000‑1600份；S2、将比例份数的水泥、膨胀剂、粘合剂与水放入搅拌筒中进行搅拌，制得水泥浆；S3、规划好基层的设计要求；S4、使用清洁工具将基底清理整洁，确保基底平整无杂物。本申请通过在碎石基层的内部材料中添加有粘合剂，并在施工时在基层的底部预先铺设上一层添加有粘合剂的水泥层作为地基，进行固定，防止出现下承层较为松散、有浮土存在的情况，基层与下承层之间的粘合紧实效果差的问题，提升道路的质量，延长道路的使用寿命，带来了更好的使用前景。
