Asphalt mixture and preparation method thereof
The invention relates to the field of road construction, and particularly discloses an asphalt mixture and a preparation method thereof. The asphalt mixture comprises the following components in parts by weight: 65-70 parts of a macadam mixture; 4.2-4.6 parts of mineral powder; 2-8 parts of an asphalt raw material; and 0.2-0.4 part of blend fiber. The blend fiber is prepared by blending the following raw materials by mass: 80-85% of wood fiber; 7-15% of polyacrylonitrile fiber; and 2-8% of polyester fiber. The preparation method comprises the following steps: stirring and drying the macadam mixture in a drying barrel, adding the mineral powder and the blend fibers, and uniformly conducting mixing to obtain a base material; and heating the asphalt raw material, conducting mixing and stirring with the base material, and uniformly conducting mixing to obtain the asphalt mixture. The asphalt mixture disclosed by the invention has excellent water stability, and an asphalt concrete pavement formed by the asphalt mixture is not easy to damage in an application process.
本申请涉及道路建设领域，具体公开了一种沥青混合料及其制备方法。一种沥青混合料，其包含以下重量份的组分：碎石混合料65‑70份；矿粉4.2‑4.6份；沥青原料2‑8份；混纺纤维0.2‑0.4份；所述混纺纤维由包含以下质量比的原料混纺制成：木质纤维80‑85%；聚丙烯腈纤维7‑15%；聚酯纤维2‑8%；其制备方法为：先将碎石混合料在烘干桶内进行搅拌烘干，并加入矿粉和混纺纤维，混合均匀得到基料；再将沥青原料加热后与基料混合搅拌，混合均匀后即可得到沥青混合料。本申请的沥青混合料具有优异的水稳定性能，且其所形成的沥青混凝土路面在应用过程中不易出现损坏。
