Fiber-reinforced high-toughness asphalt mixture and preparation method thereof
The invention relates to the technical field of asphalt mixtures, in particular to a fiber-reinforced high-toughness asphalt mixture and a preparation method thereof. The invention relates to a fiber reinforced high-toughness asphalt mixture, which is prepared from the following raw material components in percentage by mass: 7.5 to 8.5 percent of high-viscosity high-elasticity modified asphalt, 0.2 to 0.4 percent of basalt fiber and 91.1 to 92.3 percent of mineral aggregate, the mineral aggregate comprises, by mass, 65%-75% of coarse aggregate and 25%-35% of fine aggregate. According to the fiber-reinforced high-toughness asphalt mixture, the thickness of an asphalt oil film is increased, the durability, the crack resistance, the tensile strength, the shear resistance and the rutting resistance are improved, and the technical problems that an existing high-toughness asphalt mixture is poor in durability, and the use performance cannot meet the requirements are solved.
本发明涉及沥青混合料技术领域，尤其涉及一种纤维增强型高韧沥青混合料及其制备方法。一种纤维增强型高韧沥青混合料，按照质量百分比计算，其原料包括以下组分：高粘高弹改性沥青7.5％～8.5％、玄武岩纤维0.2％～0.4％和矿料91.1％～92.3％；按照质量百分比计算，所述矿料包括粗集料65％～75％和细集料25％～35％。所述纤维增强型高韧沥青混合料，沥青油膜厚度提升，耐久性能、抗裂、抗拉、抗剪和抗车辙性能提升，解决了现有高韧沥青混合料耐久性能差，使用性能无法满足需求的技术问题。
