Cement stabilized macadam mixture and preparation method thereof
The invention relates to the technical field of pavement base materials, and particularly discloses a cement stabilized macadam mixture and a preparation method thereof. The cement stabilized macadam mixture comprises water and aggregate, and is characterized by comprising the following raw materials in parts by weight: 1-5 parts of cement, 50-70 parts of macadam, 4-8 parts of fly ash, 5-15 parts of sand, 5-15 parts of stone chips, 1-3 parts of carboxymethyl cellulose, 1-3 parts of polyvinyl alcohol fiber and 4-10 parts of water. The preparation method comprises the following steps: preliminarily mixing the broken stones, the sand, the stone chips and the polyvinyl alcohol fibers, then adding the water, the cement and the modified sodium carboxymethyl cellulose, and performing secondary uniform stirring to obtain a mixture. The polyvinyl alcohol fiber cement stabilized macadam mixture disclosed by the invention can be used for building a highway pavement, and has the advantages of avoiding the cracking of cement stabilized macadam as much as possible and ensuring the stability of a pavement base course.
本申请涉及路面基层材料的技术领域，具体公开了一种水泥稳定碎石混合料及其制备方法。水泥稳定碎石混合料包括水和集料，其特征在于，其包括以下重量份的原料：水泥1‑5份、碎石50‑70份、粉煤灰4‑8份、砂5‑15份、石屑5‑15份、羧甲基纤维素1‑3份、聚乙烯醇纤维1‑3份、水4‑10份；其制备方法为：将碎石、砂、石屑、聚乙烯醇纤维初步混合，后加入水、水泥和改性羧甲基纤维素钠二次搅拌均匀，制得混合料。本申请的聚乙烯醇纤维水泥稳定碎石混合料可用于修建公路路面，其具有尽量避免水泥稳定碎石开裂的情况发生，保证路面基层的稳定性的优点。
