Composite roadbed material prepared from construction waste and preparation method of composite roadbed material
The invention discloses a composite roadbed material prepared from construction waste and a preparation method of the composite roadbed material. The composite roadbed material is prepared from the following raw materials: construction waste fine aggregate, construction waste coarse aggregate, construction waste powder, waste lime powder, volcanic pumice particles, slag powder, glass fibers, desulfurized gypsum and water. According to the invention, the construction waste is crushed and then is reused as a roadbed raw material, so that the environmental cost and labor cost during treatment of the construction waste are saved, and the construction waste is used as a renewable road building raw material, so that the cost is low, and the usage amount of soil and stones is reduced. The construction waste fine aggregate, the construction waste coarse aggregate and the construction waste powder are added, the crushed fine aggregate generated in the construction waste crushing process is effectively utilized, the utilization rate of the construction waste is greatly improved, and the construction waste aggregates with different particle sizes are mixed for use, so that gaps among the raw materials are reduced, and the overall compactness is improved; the waste lime powder and the desulfurized gypsum are added as adhesives of the roadbed material, so that the integrity of the roadbed material is improved, and the conditions such as cracking are prevented.
本发明公开了一种建筑垃圾制备的复合路基材料及其制备方法，由以下原料组成：建筑垃圾细骨料、建筑垃圾粗骨料、建筑垃圾粉料、废石灰粉、火山浮石颗粒、矿渣粉、玻璃纤维、脱硫石膏和水。本发明将建筑垃圾粉碎后作为路基原料再次利用，节省了建筑垃圾处理时的环境成本和人工成本，而且作为可再生的筑路原料，成本低廉，减少了土石的使用量。加入筑垃圾细骨料、建筑垃圾粗骨料和建筑垃圾粉料，将建筑垃圾粉碎过程中产生的粉碎细料进行有效利用，大大的提高了建筑垃圾的利用率，而且利用不同粒径的建筑垃圾骨料混合使用，减少原料间的空隙，提升整体致密性；加入废石灰粉和脱硫石膏作为路基材料的胶黏剂，提升其整体性，防止开裂等情况出现。
