Asphalt concrete filler, and asphalt concrete and preparation method thereof
The invention relates to the technical field of engineering materials, and particularly discloses an asphalt concrete filler, and asphalt concrete and a preparation method thereof. The asphalt concrete filler comprises the following raw materials in parts by weight: 14-35 parts of limestone powder, 16-39 parts of steel slag powder, 5-30 parts of cobalt powder and 0.2-0.9 part of a dispersing agent. The asphalt concrete is prepared from the filler, and the preparation method comprises the following steps: firstly drying coarse aggregate and fine aggregate, then adding the filler for multiple times, uniformly mixing, adding the above into asphalt, and stirring to obtain the asphalt concrete. The asphalt concrete filler can be used in asphalt concrete production, and has the advantages of improving the water damage resistance of asphalt concrete and prolonging the service life of the asphalt concrete.
本申请涉及工程材料的技术领域，具体公开了一种沥青混凝土填料、沥青混凝土及其制备方法。沥青混凝土填料包括以下重量份数的原料：石灰石粉14‑35份、钢渣粉16‑39份、钴粉5‑30份和分散剂0.2‑0.9份；沥青混凝土由上述填料制备获得，其制备方法为：通过先将粗骨料和细骨料烘干处理，再分多次将填料加入，混合均匀后加入沥青中搅拌，得到沥青混凝土。本申请的沥青混凝土填料可用于沥青混凝土生产中，其提高沥青混凝土的抗水害能力，延长沥青混凝土的使用寿命的优点。
