The invention discloses a high-temperature-resistant anti-rut asphalt mixture which comprises the following raw materials in parts by weight: 15-18 parts of pretreated asphalt, 30-35 parts of zinc chloride, 5-10 parts of heat conduction material, 8-12 parts of glass fiber, 5-10 parts of admixture and 90-100 parts of aggregate. The pretreated asphalt is prepared from the following raw materials in parts by weight: 8-14 parts of modified asphalt, 6-8 parts of dihydroxyl-terminated polydimethylsiloxane, 14-16 parts of polycaprolactone glycol, 2-4 parts of 1, 6-hexamethylene diisocyanate, 0.5-1 part of dibutyltin dilaurate and 4-6 parts 4, 4'-dimethyl-2, 2'-dipyridyl, and 0.5-0.8 part of 1, 4-butanediol. The preparation method is reasonable in process design and proper in component proportion, the prepared asphalt mixture has excellent anti-rutting capacity, the high-temperature stability and the water stability of the asphalt mixture are improved, and the asphalt mixture can be applied to roads with large traffic volume and more heavy-load and overload vehicles and has higher practicability.
本发明公开了一种耐高温抗车辙沥青混合料，所述沥青混合料各组分原料包括：以重量计，预处理沥青15‑18份、氯化锌30‑35份、导热料5‑10份、玻璃纤维8‑12份、掺和料5‑10份、集料90‑100份；所述预处理沥青各组分原料包括：以重量计，改性沥青8‑14份、双羟基封端聚二甲基硅氧烷6‑8份、聚己内酯二醇14‑16份、1,6‑六亚甲基二异氰酸酯2‑4份、二月硅酸二丁基锡0.5‑1份、4,4'‑二甲基‑2,2'‑联吡啶4‑6份、1,4‑丁二醇0.5‑0.8份。本发明工艺设计合理，组分配比适宜，制备得到的沥青混合料具有优异的抗车辙能力，且该沥青混合料的高温稳定性、水稳定性均得到提升，可应用于交通量大和重载、超载车辆较多的道路，具有较高的实用性。
