The invention discloses a high-temperature-resistant anti-rutting asphalt mixture and a preparation method thereof. The asphalt mixture is prepared from, by weight, 15-18 parts of pretreated asphalt,30-35 parts of zinc chloride, 5-10 parts of a heat conduction material, 8-12 parts of glass fibers, 5-10 parts of an admixture and 90-100 parts of an aggregate. The pretreated asphalt is prepared fromthe following raw materials by weight: 8 to 14 parts of modified asphalt, 6 to 8 parts of dihydroxyl-terminated polydimethylsiloxane, 14 to 16 parts of polycaprolactone glycol, 2 to 4 parts of 1,6-hexamethylene diisocyanate, 0.5 to 1 part of dibutyltin dilaurate, 4 to 6 parts of 4,4'-dimethyl-2,2'-dipyridyl and 0.5 to 0.8 part of 1,4-butanediol. The asphalt mixture is reasonable in process designand 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及其制备方法，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。
