Cement-stabilized regenerated material for pavement subbase and preparation method of cement-stabilized regenerated material
The invention discloses a cement stable regenerated material for a pavement subbase layer and a preparation method thereof. The cement stable regenerated material for the pavement subbase layer comprises the following components in parts by weight: 100 parts of regenerated ingredients, 3-10 parts of cement, 1-6 parts of silica fume, 1-15 parts of dry desulfurization ash, 1-10 parts of an additive and 5-15 parts of water. The prepared cement stable regenerated material can consume a large amount of industrial and building solid waste, the defects that a regenerated material state mixture is fast in loss, low in strength, large in dry shrinkage and prone to cracking are overcome, and the prepared pavement base cement stable regenerated material mixture is long in operation time, high in strength, low in dry shrinkage rate, good in anti-cracking performance, low in cost and suitable for large-scale popularization and application. And the preparation method and the use method are simple, and have important economic and social benefits.
本发明公开了路面底基层用水泥稳定再生材料及其制备方法，路面底基层用水泥稳定再生材料包括以下重量配比的组分：再生级配料100份、水泥3‑10份、硅灰1‑6份、干法脱硫灰1‑15份、添加剂1‑10份、水5‑15份。本发明制备的水泥稳定再生材料可消纳大量的工业以及建筑固废，解决了再生材料状态拌合物损失快、强度低、干缩大易开裂的缺陷，所制备的路面基层水泥稳定再生材料拌合物操作时间长，强度高、干缩率低，抗裂性能好，成本低，制备方法和使用方法简单，具有重要的经济及社会效益。
