Asphalt mixture and preparation method thereof
The invention relates to the field of road construction, and particularly discloses an asphalt mixture and a preparation method thereof. The asphalt mixture comprises the following components by weight: 65-75 parts of a gravel mixture; 4-6 parts of mineral powder; 2-3 parts of an asphalt raw material; 0.1-0.3 part of polyester fiber; 1.5-2.5 parts of waste rubber particles; 0.8-1.4 parts of porcelain glaze slurry; the preparation method comprises the following steps: stirring and drying the gravel mixture in a drying barrel, adding the mineral powder, the waste rubber particles and the porcelain glaze slurry, and uniformly mixing to obtain a base material; and heating the asphalt raw material, mixing and stirring with the base material, adding the porcelain glaze slurry, and uniformly mixing to obtain the asphalt mixture. The asphalt mixture has excellent temperature sudden change resistance so that a road surface formed by the asphalt mixture is not easy to crack when being rolled by relatively large gravity when the temperature change of an external environment is relatively violent.
本申请涉及道路建设领域，具体公开了一种沥青混合料及其制备方法。一种沥青混合料，其包含以下重量份的组分：碎石混合料65‑75份；矿粉4‑6份；沥青原料2‑3份；聚酯纤维0.1‑0.3份；废旧橡胶颗粒1.5‑2.5份；瓷釉浆料0.8‑1.4份；其制备方法为：先将碎石混合料在烘干桶内进行搅拌烘干，并加入矿粉、废旧橡胶颗粒和瓷釉浆料，混合均匀得到基料；再将将沥青原料加热后与基料混合搅拌，并加入瓷釉浆料，混合均匀后即可得到沥青混合料。本申请的沥青混合料具有优异的耐温急变性，进而当外界环境的温度变化较为剧烈时，使沥青混合料所形成的道路路面在受到较大重力碾压不易产生裂缝。
