Reactive dilution type regenerated cold patch material suitable for severe rain and snow environment and preparation method of reactive dilution type regenerated cold patch material
The invention belongs to the field of road maintenance engineering, and particularly relates to a reaction dilution type recycled cold patch material suitable for a severe rain and snow environment and a preparation method thereof, the reaction dilution type recycled cold patch material comprises the following raw materials by mass: 97-99 parts of an asphalt pavement reclaimed material, 1-3 parts of mineral powder, 1-1.5 parts of fiber, and 4-6 parts of cold patch asphalt; the cold patch asphalt is prepared from asphalt, an asphalt diluent, polyurethane, slaked lime and cement, wherein the mass ratio of the asphalt to the asphalt diluent to the polyurethane to the slaked lime to the cement is 100: (25-32): (3-6): (2-5): (2-5); the asphalt diluent is a mixture of 0 # diesel oil and epoxy corn oil. The early strength of the cold patch material is improved, and the cohesiveness and water stability of the cold patch material in the severe rain and snow construction environment are improved, so that the rapid repairing quality of the pavement pit slot in the severe rain and snow environment is improved.
本发明属于道路养护工程领域，具体涉及一种适用于雨雪恶劣环境下的反应稀释型再生冷补料及其制备方法，该反应稀释型再生冷补料包括以下质量份的原材料：沥青路面回收料97～99份、矿粉1～3份、纤维1～1.5份、冷补沥青4～6份；所述冷补沥青由沥青、沥青稀释剂、聚氨酯、消石灰和水泥制成，质量比为：沥青：沥青稀释剂：聚氨酯：消石灰：水泥＝100：25‑32：3‑6：2‑5：2‑5；所述沥青稀释剂为0#柴油与环氧玉米油的混合物。本发明通过提高冷补料早期强度，改善冷补料在雨雪恶劣施工环境下的粘聚性和水稳定性，进而提升路面坑槽在雨雪恶劣环境下快速修复的质量。
