Modified asphalt concrete and preparation method thereof
The invention relates to the field of asphalt concrete, in particular to modified asphalt concrete and a preparation method thereof.The modified asphalt concrete is mainly prepared from, by weight, 30-50 parts of coarse aggregate, 15-30 parts of fine aggregate, 20-30 parts of modified asphalt, 2-3 parts of nano calcium carbonate and 4-8 parts of modified rubber powder; the preparation method of the modified rubber powder comprises the following steps: 1) mixing rubber powder with an activating agent to prepare a premix; the mass ratio of the rubber powder to the activating agent is (2-3): (0.5-1.5); the activating agent is at least one of waste engine oil and soybean oil; and (2) putting the premix prepared in the step (1) into a sealed container, and activating at 60-80 DEG C for 1-2 hours, thereby obtaining the feed additive. The anti-cracking asphalt concrete has the advantage of improving the anti-cracking performance of the asphalt concrete.
本申请涉及沥青混凝土领域，更具体地说，它涉及一种改性沥青混凝土及其制备方法，主要包括如下重量份数的原料：粗骨料30‑50份、细骨料15‑30份、改性沥青20‑30份、纳米碳酸钙2‑3份、改性胶粉4‑8份；所述改性胶粉的制备方法包括如下步骤：1)：将胶粉与活化剂混合，制备成预混料；所用胶粉与活化剂的质量比为（2‑3）:（0.5‑1.5）；所用活化剂为废机油、大豆油中的至少一种；2)：在步骤1)中制备的预混料放置在密封容器内，在60‑80℃下活化1‑2h，即得。本申请具有提高沥青混凝土的抗开裂性能的优点。
