Anti-rutting asphalt concrete and preparation method thereof
The invention relates to the technical field of asphalt concrete, and discloses anti-rutting asphalt concrete and a preparation method thereof.The asphalt concrete is prepared from, by weight, 100-120 parts of asphalt, 350-370 parts of stone, 150-170 parts of river sand, 55-65 parts of filler, 10-20 parts of rubber and 12-16 parts of modified carbon fiber; the modified carbon fiber is prepared by modifying the surface of carbon fiber through a vinyl silane coupling agent to prepare vinyl silane coupling agent grafted carbon fiber, and then reacting with styrene, acrylamide and limonene under the action of an initiator and a cross-linking agent; the anti-rutting agent has the advantages that the cohesive force in the asphalt material is improved, so that the anti-rutting stability of the asphalt concrete is improved.
本申请涉及沥青混凝土的技术领域，公开了一种抗车辙沥青混凝土及其制备方法，所述沥青混凝土包括如下重量份的原料：沥青100‑120份、石子350‑370份、河砂150‑170份、填料55‑65份、橡胶10‑20份和改性碳纤维12‑16份；所述改性碳纤维通过乙烯基硅烷偶联剂将碳纤维表面改性制得乙烯基硅烷偶联剂接枝碳纤维，然后与苯乙烯、丙烯酰胺和柠檬烯在引发剂和交联剂的作用下反应制得；其具有提高沥青料内部的粘结力,从而提高沥青混凝土的抗车辙稳定性的优点。
