Cement stabilized macadam mixture and preparation process thereof
The invention discloses a cement stabilized macadam mixture which comprises the following components in parts by weight: 72-92 parts of aggregate and 8-28 parts of mortar; the aggregate comprises coarse aggregate and fine aggregate, wherein the coarse aggregate accounts for 15-40% of the total mass of the aggregate, and the fine aggregate accounts for 60-85% of the total mass of the aggregate; the particle size range of the coarse aggregate is 4-9 mm, and the particle size range of the fine aggregate is 0-4 mm; the mortar comprises water and a cementing material, wherein the water accounts for 15%-35% of the total mass of the mortar, and the cementing material accounts for 65%-85% of the total mass of the mortar; and the cementing material is Portland cement. According to the invention, the crushed stones with different particle sizes are added, so that the shrinkage coefficient is reduced; the crushed stones can be in close and maximum-area contact to the greatest extent to form the tightest skeleton structure, so that the durability of the pavement structure is improved, and the service life of the pavement is prolonged; the economic benefit, the social benefit and the environmental benefit are remarkable; waste materials such as slag and coal cinder are used for manufacturing, so that environmental pollution pressure is relieved, sustainable development is achieved, and the construction cost is reduced.
本发明公开了一种水泥稳定碎石混合料，包括以下重量份数的组分：骨料72～92份、灰浆8～28份；骨料包括粗集料、细集料，粗集料占骨料总质量的15％～40％，细集料占骨料总质量的60％～85％；粗集料的粒径范围为4～9mm，细集料的粒径范围为0～4mm；灰浆包括水、胶凝材料，水占灰浆总质量的15％～35％，胶凝材料占灰浆总质量的65％～85％；胶凝材料为硅酸盐水泥。本发明将不同粒径的碎石加入其中使干缩系数减小，碎石能够最大限度地接近，最大面积地接触，形成最紧密的骨架结构，提升路面结构的耐久性，延长路面使用寿命，具有显著的经济效益、社会效益和环境效益；利用矿渣、煤渣等废料进行制作，减轻环境污染压力，实现可持续发展，降低工程造价。
