The invention relates to an environment-friendly anti-rutting asphalt mixture and a preparation method thereof. The environment-friendly anti-rutting asphalt mixture is prepared from the following components in parts by weight: 1200 to 1500 parts of aggregate; 100 to 200 parts of mineral powder; 120 to 150 parts of asphalt; 5 to 8 parts of a film-forming agent; 1.5 to 2.0 parts of an anti-stripping agent; 200 to 500 parts of a modified recycled asphalt material; the modified recycled asphalt material is prepared by the following steps: a, pretreatment: crushing and screening a waste asphalt pavement, heating, vacuumizing at negative pressure, and freeze-drying to prepare a modified precursor; b, modification treatment: heating and mixing the modified precursor, the modified liquid and a regenerant, and vacuumizing under negative pressure to prepare a modified regenerated asphalt material; the modification liquid is composed of a hot melt colloid and a filler; the hot melt colloid is prepared from saturated polyester resin, polyamide wax and polyamide-imide. The asphalt mixture has the advantages of environmental protection and rut resistance.
本申请涉及一种环保型抗车辙沥青混合料及其制备方法。一种环保型抗车辙沥青混合料，由如下重量份数的组分组成：集料1200‑1500份；矿粉100‑200份；沥青120‑150份；成膜剂5‑8份；抗剥落剂1.5‑2.0份；改性再生沥青料200‑500份；改性再生沥青料由以下步骤制得：a、预处理：将废旧沥青路面破碎、筛分后，升温加热，再负压抽真空、冷冻干燥，制得改性前体；b、改性处理：将改性前体与改性液和再生剂加热混合，并负压抽真空，制得改性再生沥青料；改性液由热熔胶体和填料组成；热熔胶体由饱和聚酯树脂、聚酰胺蜡和聚酰胺酰亚胺组成。本申请的沥青混合料，具有环保抗车辙的优点。
