Water-damage-resistant asphalt concrete and preparation method thereof
The invention provides water damage resistant asphalt concrete and a preparation method thereof. The asphalt concrete is prepared from the following raw material components in parts by weight: 4.5 to 5.5 parts of matrix asphalt, 0.3 to 0.5 part of an anti-stripping agent, 97.5 to 99.9 parts of mineral aggregate and 0.01 to 2.5 parts of super absorbent resin, the super absorbent resin is sodium polyacrylate water absorbent resin. The preparation method comprises the following steps: S1, preparing a first material, a second material, a third material and a fourth material; and S2, preparing the asphalt concrete with water damage resistance. The method is used for solving the problem of water damage caused by flowing water migration and erosion of the asphalt pavement.
本发明提供了一种抗水损害的沥青混凝土及其制备方法，该沥青混凝土包括以下重量份数的原料组分：4.5‑5.5份基质沥青、0.3‑0.5份抗剥落剂、97.5‑99.9份矿料和0.01‑2.5份超吸水性树脂；所述超吸水性树脂为聚丙烯酸钠吸水性树脂。该制备方法包括以下步骤S1、制备第一物料、第二物料、第三物料和第四物料；步骤S2、制备抗水损害的沥青混凝土。本发明用于解决沥青路面因动水迁移和冲蚀作用而引发的水损害问题。
