Foamed asphalt cold-recycled mixture for improving pavement performance of surface layer and preparation method of foamed asphalt cold-recycled mixture
The invention discloses a foamed asphalt cold-recycled mixture for improving pavement performance of a surface layer and a preparation method thereof, and the foamed asphalt cold-recycled mixture comprises the following components in parts by mass: 5-10 parts of foamed asphalt, 15-50 parts of a waste asphalt mixture, 10-40 parts of waste cement concrete recycled aggregate, 1-2 parts of cement, 5-20 parts of mineral powder, 5-30 parts of gravel, 1-5 parts of an anti-stripping agent and 1-5 parts of a coupling agent solution. The waste asphalt mixture further contains a regenerant, the regenerant accounts for 7%-15% of the weight of asphalt in the waste asphalt mixture, the raw materials of the foamed asphalt comprise matrix asphalt, foaming water, an amine anti-stripping agent and absolute ethyl alcohol, the waste cement concrete recycled aggregates comprise recycled aggregates with nominal particle sizes of 0.36-4.75 mm, 4.75-9.5 mm, 9.5-16 mm and 16-19 mm, and the waste cement concrete recycled aggregates comprise recycled aggregates with nominal particle sizes of 0.36-4.75 mm, 4.75-9.5 mm, 9.5-16 mm and 16-19 mm. The waste asphalt mixture is graded according to the oil-containing particle size, and the weight ratio of fine waste with the oil-containing particle size of 0-6 mm, coarse waste with the oil-containing particle size of 6-16 mm, coarse aggregate and fine aggregate is 7: 3.
本发明公开了提高面层路用性能的泡沫沥青冷再生混合料及其制备方法，包括按质量份数计算的泡沫沥青5‑10份、废旧沥青混合料15‑50份、废弃水泥混凝土再生集料10‑40份、水泥1‑2份、矿粉5‑20份、碎石5‑30份、抗剥落剂1‑5份、偶联剂溶液1‑5份，所述废旧沥青混合料中还含有再生剂，所述再生剂占所述废旧沥青混合料中沥青重量的7％‑15％，所述泡沫沥青的原料包括基质沥青、发泡水、胺类抗剥落剂和无水乙醇，所述废弃水泥混凝土再生集料包括公称粒径为0.36‑4.75mm、4.75‑9.5mm、9.5‑16mm、16‑19mm的再生集料，所述废旧沥青混合料根据含油粒径划分等级，含油粒径为0‑6mm的细废料和含油粒径为6‑16mm的粗废料，粗集料与细集料的重量比为7:3。
