Phosphogypsum-based aggregate warm mix asphalt mixture
The invention provides a phosphogypsum-based aggregate warm mix asphalt mixture. The mixture comprises the following raw materials by weight percentage: 83%-91% of phosphogypsum-based aggregate, 3.0-7.0% of warm mix asphalt, 2.2%-4.7% of an admixture and 2.8%-5.3% of a heat storage agent. And a curing agent is formed by mixing one or more of sodium silicate powder, quicklime powder, calcium nitrate and hydrophilite powder. The warm mix asphalt is prepared by mixing 90-97% of matrix asphalt, 1-3% of a ferrotitanium lignosulfonate complex, 0.5-1.5% of sodium polyacrylate, 0.2-1.0% of diatomite and 1-2% of a silane coupling agent at the temperature of 110-130DEG C. The phosphogypsum-based aggregate warm mix asphalt mixture has the advantages of good performance, wide application range, convenient operation and simple preparation process; the raw materials are mainly wastes, the cost is low, the energy consumption is low, and secondary pollution to the environment is avoided.
本发明提供一种磷石膏基骨料温拌沥青混合料，该材料包括如下重量百分数的原料：磷石膏基骨料83%~91%、温拌沥青3.0~7.0%、外掺剂2.2%~4.7%和2.8%~5.3%储热剂。所述的固化剂由泡花碱粉末、生石灰粉、硝酸钙、氯钙石粉的一种和几种混合而成。所述的温拌沥青由基质沥青90‑97%、钛铁木质素磺酸盐络合物1‑3%、聚丙烯酸钠0.5‑1.5%、硅藻土0.2‑1.0%、硅烷类偶联剂1‑2%在110~130℃混合而成。本发明的磷石膏基骨料温拌沥青混合料具有性能良好、适用范围广、操作方便、制备工艺简单；原料主要为废弃物、成本小耗能低、对环境无二次污染。
