The invention relates to the field of materials for road construction, and particularly discloses an asphalt macadam mixture and a preparation method thereof. The asphalt macadam mixture is prepared from the following raw materials in parts by weight: 60 to 70 parts of light-colored asphalt cement, 70 to 80 parts of light-colored aggregate and 10 to 15 parts of anti-ultraviolet modified inorganic pigment, the uvioresistant modified inorganic pigment is obtained by modifying an inorganic pigment with epoxy resin, 4, 4 '-diaminodiphenyl sulfone and titanium dioxide; the preparation method comprises the following steps: heating the light-colored asphalt cement to 160-170 DEG C while stirring, adding the rest raw materials while stirring, and continuously stirring for 5-10 minutes at the temperature of 160-170 DEG C to obtain the asphalt macadam mixture. The asphalt macadam mixture has the advantage of improving the color durability of the asphalt macadam mixture.
本申请涉及道路施工用材料的领域，具体公开了一种沥青碎石混合料及其制备方法。一种沥青碎石混合料，包括以下重量份的原料：浅色沥青胶结料60‑70份，浅色集料70‑80份，抗紫外线改性无机颜料10‑15份；抗紫外线改性无机颜料由无机颜料经环氧树脂、4,4’‑二氨基二苯砜和二氧化钛改性得到；其制备方法为：将浅色沥青胶结料在搅拌下加热至160‑170℃，并在搅拌下加入剩余原料，在160‑170℃温度下持续搅拌5‑10min得到沥青碎石混合料。本申请一种沥青碎石混合料具有改善沥青碎石混合料颜色持久性的优点。
