Asphalt mortar doped with regenerated micro powder and novel warm mixing agent and preparation method of asphalt mortar
The invention relates to the technical field of building materials, in particular to asphalt mortar doped with regenerated micro powder and a novel warm mixing agent and a preparation method of the asphalt mortar. The asphalt mortar doped with the regenerated micro powder and the novel warm mixing agent comprises the following components in parts by weight: 100 parts of asphalt, 2-4 parts of the novel warm mixing agent and 60-120 parts of the regenerated micro powder. The recycled micro powder provided by the invention is powder particles with the particle size of less than 0.075 mm generated in the processes of crushing and processing the construction wastes and preparing the recycled aggregate, contains a large amount of hardened set cement and unhydrated cement, and has the characteristics of porosity, rough surface and the like. The recycled micro powder is used as the asphalt filler, and the high-alumina fly ash is used for preparing the warm mixing agent, so that the high-temperature performance and the rutting resistance of the asphalt can be obviously improved, the resource utilization efficiency of the construction wastes and the high-valued resource utilization of the fly ash can be greatly improved, the construction cost is reduced, and the sustainable development of the civil engineering industry is realized.
本发明涉及建筑材料技术领域，具体涉及一种掺加再生微粉和新型温拌剂的沥青胶浆及其制备方法。掺加再生微粉和新型温拌剂的沥青胶浆，按重量份计，包括以下组分：沥青100份、新型温拌剂2～4份、再生微粉60～120份。本发明提供的再生微粉是在建筑垃圾破碎加工、制备再生骨料过程中产生的粒径小于0.075mm的粉体颗粒，含有大量硬化水泥石和未水化水泥，具有多孔、表面粗糙等特性。将再生微粉作为沥青填料，利用高铝粉煤灰制备温拌剂，不仅可以明显改善沥青的高温性能和抗车辙性能，而且还可以极大地提高建筑垃圾资源化利用效率和粉煤灰的高值化资源利用，降低工程造价，实现土木工程行业可持续发展。
