Grading method of cold recycled mixture
The invention belongs to the technical field of asphalt pavement cold recycling, and particularly relates to a grading method of a cold recycled mixture. The cold recycled mixture comprises a new aggregate, a pavement milling material, cement, mineral powder, emulsified asphalt and water; the total parts by mass of the new aggregate, the pavement milling material, the cement and the mineral powderare 100 parts, and the cold recycled mixture concretely comprises, by mass, 0-50 parts of the new aggregate, 50-100 parts of the pavement milling material, 1.5-2.5 parts of the cement, 2 parts of themineral powder, 2.5-4.5 parts of the emulsified asphalt and 3-5 parts of the water. According to the production method, the strength of the pavement can be improved, the utilization rate of the old asphalt pavement is effectively increased, and green development of roads is achieved.
本发明属于沥青路面冷再生技术领域，尤其涉及一种冷再生混合料的级配方法，所述冷再生混合料包括新集料、路面铣刨料、水泥、矿粉、乳化沥青以及水；其中按质量份数计，所述新集料、路面铣刨料、水泥以及矿粉的总份数为100份，所述新集料为0‑50份，所述路面铣刨料为50‑100份，所述水泥为1.5‑2.5份，所述矿粉为2份，所述乳化沥青为2.5‑4.5份，所述水为3‑5份。该生产方法不仅能够提高路面的强度，而且还有效的提高了旧沥青路面的利用率，实现道路的绿色发展。
