The invention provides a cement stabilized macadam mixture and a pavement, and relates to the technical field of pavement paving construction. The cement stabilized macadam mixture is prepared from the following materials in parts by weight: 68 to 72 parts of coarse aggregate, 28 to 32 parts of fine aggregate, 4 parts of cement and 4.3 parts of water, wherein the particle size of the coarse aggregate is 9.5-31.5 mm, and the particle size of the fine aggregate is less than 9.5 mm. The cement stabilized macadam pavement comprises a base layer, and the base layer adopts the cement stabilized macadam mixture as a structural layer material. By adopting the cement stabilized macadam mixture as a structural layer material, on the basis of the prior art, the ratio of coarse aggregates to fine aggregates is optimized, the use amount of the coarse aggregates is increased, the use amount of the fine aggregates is reduced, and gaps among the coarse aggregates are filled with the fine aggregates, so that the gaps among the coarse aggregates are reduced while the structural strength is ensured; the effect of effectively preventing water damage can be achieved, and the service life of the pavement is prolonged.
本发明提供了一种水泥稳定碎石混合料与路面，涉及路面摊铺施工技术领域。一种水泥稳定碎石混合料，由以下重量份的物料组成：68‑72份的粗集料、28‑32份的细集料、4份水泥和4.3份水；其中，粗集料的粒径为9.5毫米至31.5毫米，细集料的粒径小于9.5毫米。一种水泥稳定碎石路面，包括基层，基层采用上述的水泥稳定碎石混合料作为结构层材料。采用上述的水泥稳定碎石混合料作为结构层材料，在现有技术的基础上，优化粗集料和细集料的配比，增加了粗集料的用量，同时减少了细集料的用量，利用细集料填充粗集料之间的间隙，在保证结构强度的同时，减少了粗集料之间的间隙，可以起到有效防止水损害的效果，延长路面的使用寿命。
