High-skid-resistance asphalt mixture and preparation method thereof
The invention relates to a high-skid-resistance asphalt mixture and a preparation method thereof, wherein the asphalt mixture comprises the components in percentage by volume: 0%-75% of limestone, 25%-90% of calcined bauxite, 6.0%-8.0% of SBS asphalt, 1.5%-3.5% of mineral powder and 0%-1% of lignin fibers. The sum of the volumes of the limestone and the calcined bauxite accounts for 90%-93% of the total volume of the asphalt mixture. The particle size of the limestone and the particle size of the calcined bauxite are both 2.36 mm-9.5 mm. The preparation method comprises the following steps: taking and heating limestone and calcined bauxite; adopting calcined bauxite with different proportions to replace limestone in an isovolumetric mode, to obtain an aggregate; and firstly, mixing the aggregate, then adding the asphalt for mixing, and then adding the mineral powder and the lignin fibers for mixing to obtain the asphalt mixture. The preparation process of the asphalt mixture is simple, the preparation cost is low, and the anti-skid durability of the pavement surface layer can be remarkably improved.
一种高抗滑性能沥青混合料及其制备方法，沥青混合料按照体积百分比，包括石灰岩0％～75％、煅烧铝矾土25％～90％、SBS沥青6.0％～8.0％、矿粉1.5％～3.5％以及木质素纤维0％～1％；所述的石灰岩和煅烧铝矾土的体积之和占沥青混合料总体积的90％～93％。所述的石灰岩和煅烧铝矾土的粒径皆为2.36mm‑9.5mm。制备方法包括以下步骤：取石灰岩和煅烧铝矾土进行加热；采用不同比例的煅烧铝矾土等体积替代石灰岩，得到集料；先将集料拌和，接着加入沥青拌和，再加入矿粉和木质素纤维拌和，得到沥青混合料。本发明沥青混合料的制备工艺简单，制备成本低廉，能显著提高路面表层抗滑耐久性。
