The invention relates to a preparation method of an asphalt mixture, which is characterized by comprising the steps of preheating an asphalt mixture stirring container to 150-170 DEG C, adding 10-15 parts by weight of asphalt and 3-5 parts by weight of rubber particles, and quickly stirring at the stirring speed of 350-450 r/min for 20-30 minutes; and preheating 70-80 parts of treated aggregate and 15-20 parts of mineral powder to 150-170 DEG C, adding into a stirring container, stirring for 10-20 minutes, heating the stirred material to 180-190 DEG C, adding 2-3 parts of glass fibers, and continuously stirring for 5-10 minutes to obtain the asphalt mixture. The anti-stripping agent can reduce the contact angle of the asphalt on the surface of the aggregate and improve the dispersion degree of the asphalt on the surface of the aggregate. Water is not easy to retain between the aggregate and the asphalt film, so that the influence of water on the mixture is reduced. The anti-stripping agent is stable and cannot be damaged by water to be dissolved or invalid.
一种沥青混合料的制备方法，其特征在于，包括以下步骤：将沥青混合料搅拌容器预热至150‑170℃，放入（重量份）沥青10‑15份和橡胶颗粒3‑5份快速搅拌，搅拌速度为350‑450r/min，搅拌时间为20‑30min；将处理后集料70‑80份和矿粉15‑20份预热至150‑170℃，加入到搅拌容器，搅拌10‑20min，将搅拌料加热至180‑190℃，加入玻璃纤维2‑3份，继续搅拌5‑10min，制得沥青混合料。抗剥落剂能够使沥青在集料表面的接触角减小，改善沥青在集料表面的分散程度。水不易分滞留在集料与沥青膜之间，减低水分对混合料的影响。本发明抗剥落剂自身稳定，不会受到水的损害而溶解或失效。
