Low-temperature-resistant matrix asphalt mixture and preparation method thereof
The invention relates to the technical field of asphalt mixtures, and particularly discloses a low-temperature-resistant matrix asphalt mixture and a preparation method thereof. The matrix asphalt mixture is prepared from the following components in parts by weight: 74 to 82 parts of macadam, 13 to 15 parts of machine-made sand, 10 to 12 parts of solid waste-based mineral powder, 5.9 to 7.9 parts of matrix asphalt and 0.3 to 2 parts of lignin fiber. According to the invention, the matrix asphalt is used as a cementing material, and the sodium lignin sulfonate and the solid waste powder are processed into the solid waste-based mineral powder through wet ball milling, so that the matrix asphalt and the mineral powder have good binding force, and the cohesiveness of the matrix asphalt is enhanced, so that the formed asphalt mixture has good low-temperature resistance.
本申请涉及沥青混合料技术领域，具体公开了一种耐低温基质沥青混合料及其制备方法。所述基质沥青混合料包括如下重量份的组分：碎石74‑82份，机制砂13‑15份，固废基矿粉10‑12份，基质沥青5.9‑7.9份，木质素纤维0.3‑2份。本申请以基质沥青作为胶结料，并通过湿法球磨将木质素磺酸钠和固废粉体加工为固废基矿粉，使基质沥青与矿粉之间具备了良好的结合力，而且加强了基质沥青的粘聚性，因此沥青混合料成型之后能够具有较好的耐低温性能。
