Water-resistant asphalt concrete and preparation method thereof
The invention relates to the technical field of asphalt concrete, and discloses water-resistant asphalt concrete and a preparation method thereof, the asphalt concrete comprises the following raw materials by weight: 120-150 parts of asphalt, 10-14 parts of a carbon fiber-hydrogel composite material, 300-350 parts of stone, 100-150 parts of river sand and 50-70 parts of a filler; the carbon fiber-hydrogel composite material 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 the vinyl silane coupling agent grafted carbon fiber with a vinyl silane coupling agent, hydroxyethyl methylacrylate and N-vinyl pyrrolidone under the action of an initiator and a cross-linking agent. The waterproof agent has the advantages of improving the water resistance of the asphalt concrete and prolonging the service life of the asphalt concrete.
本申请涉及沥青混凝土的技术领域，公开了一种耐水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120‑150份、碳纤维‑水凝胶复合材料10‑14份、石子300‑350份、河砂100‑150份和填料50‑70份；所述碳纤维‑水凝胶复合材料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，然后与乙烯基硅烷偶联剂、甲基丙烯酸羟乙酯和N‑乙烯基吡咯烷酮在引发剂和交联剂的作用下反应制得；其具有提高沥青混凝土的耐水性，延长沥青混凝土的使用寿命的优点。
