Waterborne epoxy resin modified emulsified asphalt cold patch material for rapid road repair and preparation method thereof
The invention relates to a waterborne epoxy resin modified emulsified asphalt cold patch material for rapid road repair and a preparation method thereof. The cold patch material comprises a cementingmaterial and a mineral aggregate. The cementing material comprises the following components in parts by weight: 80-84 parts of cationic emulsified asphalt, 16-20 parts of waterborne epoxy resin emulsion, 4-5 parts of an amine curing agent, 20-22 parts of water glass and 0.5-2.0 parts of an auxiliary agent. The mineral aggregate is prepared from the following components in parts by weight: 50-52 parts of coarse aggregate, 40-42 parts of fine aggregate, 4.5-5.0 parts of composite cement, 2.4-2.8 parts of metakaolin and 0.6-0.7 parts of slag. The mass ratio of the cementing material to the mineral aggregate is (9-10): 100. The cold patch material is high in early strength, rapid in later strength formation, firm in combination with an old pavement, capable of being constructed at room temperature and low temperature, capable of rapidly opening traffic, good in pavement performance and suitable for pre-maintenance, local repair and later maintenance of an asphalt pavement.
本发明涉及一种道路快速修补用水性环氧树脂改性乳化沥青冷补料及其制备方法，该冷补料包括胶结料和矿料，所述胶结料包括以下重量份数的组分：阳离子乳化沥青80‑84份、水性环氧树脂乳液16‑20份、胺类固化剂4‑5份、水玻璃20‑22份、助剂0.5‑2.0份；所述矿料包括以下重量份数的组分：粗骨料50‑52份、细集料40‑42份、复合水泥4.5‑5.0份、偏高岭土2.4‑2.8份、矿渣0.6‑0.7份；胶结料与矿料的质量比为9‑10:100。该冷补料早期强度高、后期强度形成快，与旧路面结合牢固，可在室温及低温下施工，并能快速开放交通，具有良好的路用性能，适用于沥青路面的预养护、局部修补和后期养护。
