High-water-stability granite stone powder-based road base material and preparation method thereof
The invention discloses a high-water-stability granite stone powder-based road base material which comprises the following components in parts by weight: 100 parts of waste granite stone powder; 3-8 parts of cement; 0.5-1 part of a multifunctional water stabilizer; 10 to 19 parts of water; the preparation method of the multifunctional water stabilizer comprises the following steps: preparing a mixed solution of acrylic monomers, dropwise adding an aqueous solution of nano sol while stirring, and stirring and mixing for 20-40 minutes; raising the temperature to 80-90 DEG C, adding an aqueous solution of ammonium persulfate, and reacting for 1-2 hours to obtain a multifunctional water stabilizer; according to the invention, the multifunctional water stabilizer is used for making up the defects of the granite stone powder road base material, so that the absorption amount of the granite stone powder can be increased, and the water stability of the road base material is remarkably improved on the basis of meeting the engineering index requirements.
本发明公开了一种高水稳性花岗岩石粉基道路基层材料，组成按重量份数计如下：废弃花岗岩石粉100份；水泥3‑8份；多功能水稳剂0.5‑1份；水10‑19份；所述多功能水稳剂的制备方法包括以下步骤：制备丙烯酸类单体的混合液，搅拌下滴加纳米溶胶的水溶液，搅拌混合20‑40分钟；升温至80℃‑90℃加入过硫酸铵的水溶液，反应1‑2小时，得到多功能水稳剂；本发明用多功能水稳剂弥补花岗岩石粉道路基层材料的不足，不仅能提高花岗岩石粉消纳量的，同时在满足工程指标要求基础上显著提升道路基层材料的水稳性。
