The invention discloses a high-stability asphalt mixture and a preparation method thereof, and relates to the technical field of asphalt mixtures. The high-stability asphalt mixture comprises the following components in parts by weight: 10-15 parts of modified asphalt, 5-10 parts of mineral powder, 150-200 parts of coarse aggregate and 15-30 parts of fine aggregate, and the modified asphalt is obtained by carrying out composite modification on matrix asphalt through carbonized rice hull powder and PPA. The preparation method comprises the following steps: S1, adding the coarse aggregate, the fine aggregate and the mineral powder into a drying barrel, and drying at the speed of 1000-1500rpm and the temperature of 120-170 DEG C until the weight is constant, and S2, pouring the mixture into astirring cylinder, adding the modified asphalt heated to 150-170 DEG C, and stirring at the rotating speed of 600-800 r/min for 30-45 min to obtain the modified asphalt. The asphalt mixture obtainedin the invention has the advantages of high stability, high strength and good anti-rutting performance.
本申请公开了一种高稳定度沥青混合料及其制备方法，涉及沥青混合料技术领域。其技术要点是：该高稳定度沥青混合料，按重量份数计包括：改性沥青10‑15份；矿粉5‑10份；粗集料150‑200份；细集料15‑30份；所述改性沥青由基质沥青经过碳化稻壳粉和PPA复合改性得到。其制备方法为：S1，将粗集料、细集料和矿粉加入到烘干桶中，于1000‑1500rpm、120‑170℃下烘干至恒重；S2，将上述混合物倒入搅拌缸中，加入加热至150‑170℃的改性沥青，于600‑800r/min转速下搅拌30‑45min，即得。本申请得到的沥青混合料稳定度高、强度高、抗车辙性能好。
