Separated regenerated flexible base material and preparation method thereof
The invention discloses a separated regenerated flexible base material and a preparation method thereof, and belongs to the technical field of pavement materials. The separated regenerated flexible base material comprises the raw materials in parts by weight: 65 to 75 parts of a coarse aggregate, 25 to 35 parts of a fine aggregate, 3 to 5 parts of mineral powder, 1.5 to 2.5 parts of matrix asphalt, 3 to 5 parts of rock asphalt and self-healing microcapsules of which the weight is 3 to 5% that of the asphalt. According to the separated regenerated flexible base material, the rock asphalt and the self-healing microcapsules are simultaneously used in the raw materials, so that the rut resistance and the crack resistance of the flexible base material can be effectively improved, the cracking in the operation process is reduced, and the durability of a pavement is improved. The preparation method can be used for mixing the raw materials according to the required gradation, and is simple andeasy to operate.
本发明公开了一种分离式再生柔性基层材料及其制备方法，属于路面材料技术领域。按重量份数计，该分离式再生柔性基层材料的原料包括65‑75份粗集料、25‑35细集料、3‑5份矿粉、1.5‑2.5份基质沥青、3‑5份岩沥青以及重量为沥青重量的3‑5％的自愈合微胶囊。上述分离式再生柔性基层材料通过在原料中同时使用岩沥青和自愈合微胶囊，可有效提升柔性基层材料的抗车辙性能以及抗裂性能，减少运营过程中的开裂，提高路面的耐久性能。其制备方法可按所需级配混合上述原料，该方法简单，易操作。
