Road base material and preparation method thereof
The invention discloses a road base material and a preparation method thereof, and belongs to the field of road materials. Aiming at the problems of low strength and low utilization rate when iron tailings are applied to the field of roads in the prior art, the invention provides the road base material which comprises the following components in parts by mass: 30-70 parts of soil, 30-70 parts of iron tailing sand, 0-15 parts of water, 1-5 parts of a catalyst and 1-5 parts of a soil stabilizer. An alkaline environment is provided for the whole mixture through the catalyst, the activity of the iron tailing sand and the soil is excited to react, the strength of the whole mixture is improved, and the utilization rate of the iron tailing sand is increased; the electron polarity of the surfacesof soil particles is changed through the soil stabilizer, so that soil is easy to compact and stabilize, then iron tailing sand is effectively wrapped, and the stability of the whole mixture is improved; and the preparation method is simple in process, does not need to use large equipment, does not generate wastewater and waste in the whole preparation process, is green and environment-friendly, and has a relatively high application prospect.
本发明公开了一种道路基层材料及其制备方法，属于道路材料领域。针对现有技术中铁尾矿应用道路领域时强度较低和利用率不高的问题，本发明提供一种道路基层材料包括按质量份数计的如下组分：30‑70份土壤，30‑70份铁尾矿砂，0‑15份水，1‑5份催化剂，1‑5份土体稳定剂。通过催化剂为整体混合料提供碱性环境，激发铁尾矿砂与土壤的活性使二者发生反应提高整体混合料的强度，提高铁尾矿砂的利用率；通过土体稳定剂改变土壤颗粒表面电子极性，使土壤易于压实和稳定，继而有效包裹铁尾矿砂，提高整体混合料的稳定性；且本发明所述的制备方法工艺简单，无需借助大设备的投入使用，整个制备过程无废水废物产生，绿色环保，具有较高的应用前景。
