Calcium carbonate whisker and red mud composite modified OGFC asphalt mixture and preparation method thereof
The invention relates to the technical field of assembled base pavements, provides a calcium carbonate whisker and red mud composite modified OGFC asphalt mixture and a preparation method thereof, and provides a calcium carbonate whisker and red mud composite modifier and a preparation method thereof, the calcium carbonate whisker and red mud composite modifier comprises 10-20 parts of calcium carbonate whisker, 10-20 parts of fiber, 60-80 parts of phosphogypsum, 50-70 parts of red mud, and 5-10 parts of a coupling agent. 20 to 30 parts of a direct vat set high-viscosity asphalt modifier; the calcium carbonate whisker and red mud composite modifier is added into the OGFC asphalt mixture, the durability of the asphalt mixture can be effectively improved according to the embodiment and contrast experiment verification, and meanwhile other pavement performance is good. The composite modifier disclosed by the invention is prepared from the calcium carbonate whiskers prepared from the ardealite and the red mud, and according to the embodiment and contrast experiment verification, the recycling of the ardealite and the red mud is effectively promoted, and the environment protection and the resource recycling are facilitated.
本发明涉及本发明涉及装配式基层路面技术领域，提供一种碳酸钙晶须与赤泥复合改性OGFC沥青混合料及制备方法，并提供了碳酸钙晶须与赤泥复合改性剂及制备方法，包括碳酸钙晶须10‑20份，纤维10‑20份，磷石膏60‑80份，赤泥50‑70份，偶联剂5‑10份，直投式高粘沥青改性剂20‑30份；本发明采用碳酸钙晶须与赤泥复合改性剂加入到OGFC沥青混合料中，经实施例与对比例实验验证，可以有效的提高沥青混合料的耐久性，同时其他路用性能良好。本发明的复合改性剂是基于磷石膏制备的碳酸钙晶须及赤泥制备而成，经实施例与对比例实验验证，有效的促进磷石膏及赤泥的再生利用，有助于环境的保护与资源的再生利用。
