Construction method of large-thickness cement stabilized macadam base
The invention discloses a construction method of a large-thickness cement stabilized macadam base. The large-thickness cement stabilized macadam base is prepared from the following raw materials in parts by mass: 80-85 parts of coarse aggregate, 6-10 parts of fine aggregate, 5-8 parts of cement, 1-3 parts of an expanding agent, 1-2 parts of a composite reinforcing agent and 7-12 parts of water. The beneficial effects are that through the combination ratio of the coarse aggregate and the fine aggregate, the addition of the expanding agent and the composite reinforcing agent, and the construction process of the macadam base, the shrinkage characteristic of the cement stabilized macadam is effectively improved, the dry shrinkage and temperature shrinkage resistance of the cement stabilized macadam base is improved, the mechanical strength of the base is improved, and the comprehensive performance is improved; and meanwhile, construction procedures are reduced, the construction period is shortened, and the production and construction efficiency and the finished product quality are improved.
本发明公开了一种大厚度水泥稳定碎石基层施工方法，该大厚度水泥稳定碎石基层由以下质量份数的原料制成：粗集料80‑85份、细集料6‑10份、水泥5‑8份、膨胀剂1‑3份、复合增强剂1‑2份、水7‑12份。有益效果：通过粗集料、细集料的组合配比，膨胀剂和复合增强剂的添加，以及碎石基层的施工工艺，有效地改善水泥稳定碎石的收缩特性，提高了水泥稳定碎石基层抵抗干燥收缩和温度收缩的能力，提高基层的力学强度，综合性能得到改善，同时减少了施工工序、缩短施工周期，提高生产和施工效率及成品质量。
