Fiber-reinforced cement fly ash stabilized full-recycled brick-concrete aggregate pavement base material and preparation method thereof
The invention provides a fiber-reinforced cement fly ash stabilized full-recycled brick-concrete aggregate pavement base material and a preparation method thereof. The pavement base material is composed of full-recycled brick-concrete aggregate, cement, fly ash, water, fiber and a water reducing agent, and the pavement base material comprises the following components by weight: 800-1000 parts of full-recycled brick-concrete aggregate, 24 to 70 parts of cement, 8.0 to 20 parts of fly ash, 120 to 170 parts of water, 0.4 to 1.0 part of fiber, and 0.2-0.7 part of a water reducing agent. Accordingto the pavement base material provided by the invention, the full-recycled brick-concrete aggregate generated by dismantling the brick-concrete building is used for completely replacing natural sandstone, the road base material is rich in raw materials, low in cost, environment-friendly and economical, and has high tensile strength, dry shrinkage deformation resistance and good working performanceon the basis of meeting various technical requirements of current specifications on a road base, and the service life of a road is effectively prolonged.
本发明提供了一种纤维增强水泥粉煤灰稳定全再生砖混骨料路面基层材料及其制备方法，所述路面基层材料由全再生砖混骨料、水泥、粉煤灰、水、纤维和减水剂组成，按重量份包括：全再生砖混骨料800‑1000重量份；水泥24‑70重量份；粉煤灰8.0‑20重量份；水120‑170重量份；纤维0.4‑1.0重量份；减水剂0.2‑0.7重量份。本发明提供的路面基层材料将拆除砖混类建筑物产生的全再生砖混骨料全部替代天然砂石，原料丰富、成本低廉、环保经济，在满足现行规范对道路基层的各项技术要求的基础上，还具有较高抗拉强度、抗干缩变形能力以及良好的工作性能，有效延长道路适用寿命。
