Modified asphalt concrete and preparation method thereof
The invention relates to the technical field of asphalt concrete, and particularly discloses modified asphalt concrete and a preparation method thereof. The modified asphalt concrete is prepared from the following components in parts by weight: 20-25 parts of matrix asphalt; 5-10 parts of a modifier; 40 -50 parts of filler; 300 -400 parts of aggregate; 5-10 parts of a fiber filler; 2-4 parts of polyethylene wax; 3-8 parts of monodisperse silicon dioxide microspheres; and 0.5-1 part of a coupling agent. The modified asphalt concrete disclosed by the invention has relatively good high-temperature rutting resistance and low-temperature cracking resistance.
本申请涉及沥青混凝土技术领域，具体公开了一种改性沥青混凝土及其制备方法。改性沥青混凝土按重量份数计算，由如下组分组成：基质沥青20‑25份；改性剂5‑10份；填料40‑50份；集料300‑400份；纤维填料5‑10份；聚乙烯蜡2‑4份；单分散二氧化硅微球3‑8份；偶联剂0.5‑1份。本申请的改性沥青混凝土具有较好的高温抗车辙性能和低温抗开裂性能。
