Cement stabilized macadam base composition and preparation and construction process thereof

The invention relates to the field of cement stabilized macadam, and particularly discloses a cement stabilized macadam base composition and a preparation and construction process thereof. The cement stabilized macadam base composition is prepared from the following raw materials in parts by weight: 50 to 60 parts of cement, 900 to 1000 parts of graded macadam, 40 to 50 parts of water, 0.2 to 0.3 part of molasses, 0.8 to 1.2 parts of polystyrene/polyester blending modified steel fiber and 0.5 to 1 part of nano molybdenum disulfide modified polyvinyl alcohol. The cement stabilized macadam base provided by the invention not only has relatively high compressive strength and splitting strength, but also has relatively high temperature shrinkage performance and dry shrinkage performance, and meets market requirements. 本申请涉及水泥稳定碎石领域，具体公开了一种水泥稳定碎石基层组合物及其制备和施工工艺。水泥稳定碎石基层组合物包括以下重量份的原料制备而成：水泥50-60份、级配碎石900-1000份、水40-50份、糖蜜0.2-0.3份、聚苯乙烯/聚酯共混改性钢纤维0.8-1.2份、纳米二硫化钼改性聚乙烯醇0.5-1份。本申请中的水泥稳定碎石基层不仅具有较高的抗压强度、劈裂强度，还具有较高的温缩性能、干缩性能，符
