Regenerated micro-surfacing and preparation method thereof
The invention relates to the technical field of pavement materials, in particular to a regenerated micro-surfacing and a preparation method thereof.The micro-surfacing comprises fine separation mineral aggregate, a regenerant, modified emulsified asphalt, a water-based polymer emulsion modifier, cement and water, the regenerant accounts for 0.2%-3.0% of the fine separation mineral aggregate, the modified emulsified asphalt accounts for 4%-10% of the fine separation mineral aggregate, the water-based polymer emulsion modifier accounts for 0.5%-1.5% of the fine separation mineral aggregate, and the cement accounts for 0.5%-1.5% of the fine separation mineral aggregate. The dosage of the water-based polymer emulsion modifier is 0.5%-2.5% of asphalt in the modified emulsified asphalt; the use amount of the cement is 1.0%-2.0% of the fine separation mineral aggregate; the use amount of water is 4-10% of the fine separation mineral aggregate; the fine separation mineral aggregate is prepared from an old asphalt mixture. According to the method, the micro-surfacing is prepared by taking the full-proportion fine separation mineral aggregate prepared from the old asphalt mixture as the raw material, so that the old asphalt mixture is effectively recycled, the micro-surfacing cost is reduced, and meanwhile, the problem that the micro-surfacing is loose and runs in the initial forming stage can be solved.
本发明涉及路面材料技术领域，尤其涉及一种再生微表处及其制备方法，微表处包括精细分离矿料、再生剂、改性乳化沥青、水性聚合物乳液改性剂、水泥和水，再生剂用量为精细分离矿料的0.2％‑3.0％，改性乳化沥青用量为精细分离矿料的4％‑10％，水性聚合物乳液改性剂用量为改性乳化沥青中沥青的0.5％‑2.5％；水泥用量为精细分离矿料的1.0％‑2.0％；水用量为精细分离矿料的4％‑10％；精细分离矿料是由旧沥青混合料制备得到。本发明以旧沥青混合料制备的全比例精细分离矿料为原料制备出微表处，实现旧沥青混合料的有效再利用，在降低微表处成本的同时，能解决微表处初期成型阶段松散跑料的问题。
