The invention discloses a preparation process of a ceramsite asphalt pavement material. The preparation proces comprises the following steps: preparing the following raw materials in parts by weight:30-50 parts of asphalt, 1-2 parts of modified nano filler, 10-13 parts of modified shale ceramsite, 5-10 parts of SBS modifier, 3-5 parts of basalt fiber, 2-4 parts of diatomite, 5-10 parts of rubberpowder, 0.3-0.5 part of dispersing agent, 0.1-0.3 part of cross-linking agent and 0.1-0.3 part of antioxidant; the ceramsite asphalt pavement material is prepared by mixing the modified shale ceramsite, the modified nano-filler, asphalt and other fillers, and the modified nano-filler is added into the ceramsite asphalt pavement material, so that the mechanical property, barrier property and thermal stability of the ceramsite asphalt pavement material are improved, and the ceramsite asphalt pavement material has fatigue resistance, low-temperature crack resistance and water stability by utilizing a special physical structure of the diatomite and high damping and shock absorption characteristics of the basalt fibers.
本发明公开了一陶粒沥青路面材料的制备工艺，包括准备以下重量份的原料，沥青30‑50份、改性纳米填料1‑2份、改性页岩陶粒10‑13份、SBS改性剂5‑10份、玄武岩纤维3‑5份、硅藻土2‑4份、橡胶粉5‑10份、分散剂0.3‑0.5份、交联剂0.1‑0.3份、抗氧剂0.1‑0.3份，本发明通过将改性页岩陶粒、改性纳米填料和沥青以及其他填充物混合，制备出一种陶粒沥青路面材料，将改性纳米填料加入本发明陶粒沥青路面材料中，提高陶粒沥青路面材料的力学性能、阻隔性能和热稳定性能，利用硅藻土特殊的物理结构和玄武岩纤维的高阻尼、减震特性使该陶粒沥青路面材料具有耐疲劳性能和低温抗裂性能和水稳定性。
