High-performance cold patch asphalt mixture and preparation method thereof
The invention discloses a high-performance cold patch asphalt mixture and a preparation method thereof. The high-performance cold patch asphalt mixture comprises the following raw material components: cold patch liquid and aggregate, wherein the mass dosage of the cold patch liquid is 5.05-5.15% of the mass of the aggregate; the cold supplementing liquid is prepared from the following raw materials: 80 to 83 parts of asphalt, 16 to 20 parts of diesel oil, 1 to 2 parts of linoleic acid, 1 to 2 parts of hydrogenated rosin polyethylene glycol stearate, 5 to 10 parts of acrylic acid rosin epoxy resin, 0.05 to 0.1 part of aluminum trichloride and 1 to 1.5 parts of SBR (Styrene Butadiene Rubber) latex; the parts are parts by mass. According to the invention, normal-temperature mixing is realized, aggregate heating is not needed, fuel is saved, gas emission is avoided, production cost is reduced, and environmental protection benefits are improved; the high-performance cold patch asphalt mixture is good in adhesion, good in water stability, high in strength, free of loosening and peeling under the action of vehicle loads and long in service life; the construction workability and the storage stability of the cold patch material are improved, no special requirement for the operation environment exists, and the cold patch material is directly put into a pit slot to be properly rolled when the pit slot is repaired.
本发明公开了一种高性能冷补沥青混合料及其制备方法。一种高性能冷补沥青混合料的原料组分包括：冷补液和骨料，冷补液的质量用量为骨料质量的5.05～5.15％；冷补液的原料组成包括：沥青80～83份，柴油16～20份，亚油酸1～2份，氢化松香硬脂酸聚乙二醇酯1～2份，丙烯酸松香环氧树脂5～10份，三氯化铝0.05～0.1份和SBR胶乳1～1.5份；所述份数为质量份数。本发明实现常温拌合，无需加热骨料，节省燃料，无气体排放，减少生产成本，提高环保效益；高性能冷补沥青混合料的粘附性好，水稳定性好，强度高，在车辆荷载的作用下不出现松散、剥落，使用寿命长；提高了冷补材料的施工和易性和储存稳定性，对操作环境无特殊要求，在修补坑槽时直接将冷补材料放入坑槽内做适当碾压即可。
