Phosphogypsum rapid grouting molding road stable base and preparation method thereof
The invention relates to the technical field of bulk solid waste and roads, and provides an ardealite rapid grouting forming road stable base layer and a preparation method thereof.The preparation method comprises the steps that ardealite ceramsite with the softening coefficient larger than or equal to 85% is paved, and a road stable base layer aggregate framework with the framework porosity larger than or equal to 30% is formed; and pouring modified ardealite slurry of which the fluidity is greater than or equal to 140mm and the water consumption is 35-55% into the aggregate by adopting a grouting method. According to the invention, the specific ardealite ceramsite and the specific ardealite slurry are quickly and efficiently used for the construction of the road stable base by adopting a grouting method for the first time, and the constructed road stable base is good in molding and stable in quality and has the characteristic of quickly opening traffic. And the road stable base course has the characteristics of no mixing and same-cycle service life, is convenient to fully recycle and reuse, and has very important significance on large-scale and high-quality application of industrial solid waste phosphogypsum.
本发明涉及大宗固废及道路技术领域，提供一种磷石膏快速灌浆成型道路稳定基层及其制备方法，该制备方法包括：摊铺软化系数大于等于85％的磷石膏陶粒，形成骨架孔隙率大于等于30％的道路稳定基层骨料骨架；采用灌浆法向所述骨料中灌入流动度大于等于140mm且用水量为35～55％的改性磷石膏浆料。本发明首次将特定的磷石膏陶粒和特定的磷石膏浆料，采用灌浆法快速高效地用于道路稳定基层施工，施工后的道路稳定基层成型好、质量稳定，具备快速开放交通的特点。且该道路稳定基层具有免拌和、同周期寿命的特点，便于全回收再使用，对于工业固废磷石膏的规模化、高质应用，具有十分重要的意义。
