Repair material for repairing road cracks, repair method and preparation method
The invention discloses a preparation method of a cold mixing type traceless repairing material for repairing road cracks, which comprises the following steps: putting SBS (styrene-butadiene-styrene) modified emulsified asphalt into a stirring barrel, slowly and sequentially adding petroleum resin emulsion, acrylic emulsion and/or polyurethane emulsion and water while stirring, then adding auxiliaries, uniformly stirring, and packaging to obtain a road crack repairing component A; cement and fine sand are evenly mixed in a mixing stirrer and then packaged, the fine sand is selected from materials of the same type as a crack repairing pavement, and a road crack repairing component B is obtained; in a construction site, a road crack repairing component A and a road crack repairing component B are mixed according to the weight ratio of 1: (0.2-2) and uniformly stirred, and then the flowable cold-mixing type traceless repairing material for repairing road cracks within four hours is formed. The repair material disclosed by the invention has the characteristics of strong adsorption and adhesion with the cracked section of the pavement, large elongation at break, high tensile strength, strong adaptability, high temperature resistance, wear resistance, pollution resistance and excellent durability.
本发明公开了一种公路裂缝修补用的冷拌型无痕修复材料的制备方法，包括：将SBS改性乳化沥青放入搅拌桶中，边搅拌边缓慢依次加入石油树脂乳液、丙烯酸乳液和/或聚氨酯乳液和水，然后加入助剂，搅拌均匀后包装，得到公路裂缝修补A组分；将水泥、细砂在混合搅拌机中混合均匀后包装，细砂选用与裂缝修补路面同种类型的材料，得到公路裂缝修补B组分；在施工现场，将公路裂缝修补A组分和所述公路裂缝修补B组分按重量配比为1:0.2～2混合并搅拌均匀后，形成在四个小时内对公路裂缝进行修补的可流动冷拌型无痕修复材料。本发明的修复材料具有与路面开裂断面吸附粘结力强、断裂延伸率大、拉伸强度高、适应性强、耐高温、耐磨、抗污、耐久性优良的特点。
