Flowable ultrahigh-RAP-mixing-amount thermally recycled asphalt mixture and preparation method thereof
The invention belongs to the technical field of compositions of asphalt materials, and particularly relates to a hot recycled asphalt mixture with ultrahigh RAP mixing amount. The hot recycled asphalt mixture with the ultrahigh RAP mixing amount is prepared from a 0-10mm asphalt recycled material, mineral powder and a reinforcing agent. The recycled asphalt mixture is free of gaps, the old material mixing amount reaches 80% or above, the asphalt mortar content reaches 25% or above, the performance of the recycled asphalt mixture is insensitive to old asphalt material gradation, quality variability and aging variability, new asphalt and old asphalt can be fully fused, the recycled asphalt mixture has excellent waterproof performance and other pavement performance, and self-leveling construction is achieved.
本发明属于沥青材料的组合物技术领域，具体涉及一种流动性超高RAP掺量热再生沥青混合料。所述流动性超高RAP掺量热再生沥青混合料，由0～10mm沥青回收料、矿粉和增强剂组成。该再生沥青混合料没有空隙，旧料掺量达到80％以上，沥青胶浆含量达到25％以上，其性能对沥青旧料级配、质量变异性和老化变异性不敏感，新旧沥青能够充分融合，具有优良的防水性能和其它路用性能，自流平施工。
