Environment-friendly cold-mixed recycled asphalt mixture and preparation method and application thereof
The invention relates to the technical field of asphalt mixture preparation, in particular to an environment-friendly cold-mixed recycled asphalt mixture and a preparation method and application thereof. The environment-friendly cold-mixed recycled asphalt mixture consists of the following components in parts by weight: 3.0-4.5 parts of modified emulsified asphalt; 1.0-2.0 parts of cement; 2.0-3.0 parts of water; 3-8 parts of a new aggregate; 80-100 parts of a waste asphalt reclaimed material; and 2-5 parts of mineral powder, wherein the modified recycled asphalt is prepared from the following components in parts by weight: 50-80 parts of asphalt, 10-15 parts of waste building pipes, 3-5 parts of an SBS modifier, 1-5 parts of an emulsifier and 0.5-1.5 parts of a stabilizer. The environment-friendly cold-mixed recycled asphalt mixture disclosed by the invention is high in waste utilization rate, reduces the production cost, has good Marshall stability and strength, and is high in safety and is not easy to cause the phenomena of ruts, upheaval and the like when being applied to road maintenance and road construction.
本申请涉及沥青混合料制备技术领域，尤其涉及一种环保型冷拌再生沥青混合料，其制备方法及应用。一种环保型冷拌再生沥青混合料，由如下重量份数的组分组成：改性乳化沥青3.0‑4.5份；水泥1.0‑2.0份；水2.0‑3.0份；新集料3‑8份；废旧沥青回收料80‑100份；矿粉2‑5份；改性再生沥青按重量份数计算，由沥青50‑80份、废弃建筑管材10‑15份、SBS改性剂3‑5份、乳化剂1‑5份和稳定剂0.5‑1.5份组成。本申请的环保型冷拌再生沥青混合料其对废弃物利用率高的同时，降低了生产成本，且具有良好的马歇尔稳定度和强度，应用于道路养护和道路施工时，安全性高、不易出现车辙、拥包等现象。
