Cement stabilized macadam mixed material and preparation method thereof
The invention discloses a cement stabilized macadam mixed material and a preparation method thereof, and belongs to the technical field of buildings, and the mixed material is prepared by mixing aggregate, cement, regenerated fine aggregate, a polycarboxylic acid water reducer, a modified reinforcing agent and water. Wherein the aggregate is formed by mixing limestone, basalt and recycled coarse aggregate, and the recycled fine aggregate comes from crushed concrete or bricks. The preparation method comprises the following steps: mixing the raw materials in a vibration mixer, paving, rolling and compacting to form the base layer, and covering and curing by adopting geotechnical cloth. Compared with the prior art, the modified reinforcing agent is added, so that the dry shrinkage coefficient of the mixed material is effectively reduced, the compressive strength and the splitting strength are remarkably improved, and the stability and the durability of a road base are enhanced. In addition, cyclic utilization of the building waste is further promoted, and remarkable environmental protection and economic benefits are achieved.
本发明公开了一种水泥稳定碎石混合材料及其制备方法，属于建筑技术领域，该混合材料由骨料、水泥、再生细集料、聚羧酸减水剂、改性增强剂和水混合而成。其中，骨料由石灰岩、玄武岩和再生粗集料混合，再生细集料来源于破碎的混凝土或砖块。本发明的制备方法包括在振动搅拌机中拌和原料，摊铺、碾压、压实形成基层，并采用土工布覆盖养护。与现有技术相比，本发明通过改性增强剂的加入，有效降低了混合材料的干缩系数，同时显著提高了抗压强度和劈裂强度，增强了道路基层的稳定性和耐久性。此外，本发明还促进了建筑废料的循环利用，具有显著的环保和经济效益。
