The invention relates to a Tricenda Lake modified asphalt and wet-process fully-recycled asphalt mixture and a preparation method thereof. The preparation method of the Tricenda lake modified asphalt comprises the following steps: respectively preheating the matrix asphalt and the Tricenda lake asphalt, mixing the matrix asphalt and the Tricenda lake asphalt according to a doping ratio, and heating and stirring the matrix asphalt and the Tricenda lake asphalt to obtain the Tricenda lake modified asphalt. The preparation method of the wet-process fully-recycled asphalt mixture comprises the following steps: feeding crushed recycled materials into a mixing plant according to an asphalt-aggregate ratio, and heating and carrying out dry mixing; adding the modified asphalt of the Tricinda lake asphalt into a mixing plant, and stirring at a controlled temperature; and finally, discharging at high temperature to obtain the wet-process fully-recycled asphalt mixture. Compared with a conventional asphalt mixture regeneration method in the prior art, the method provided by the invention has the advantages that a regenerant is replaced by the Tarenda Lake modified asphalt, the 100% fully-regenerated asphalt mixture can be realized, and the high-temperature stability, the low-temperature crack resistance, the water stability and the durability which are better than those of the regenerant and matrix asphalt or common SBS modified asphalt can be obtained.
本发明涉及一种特立尼达湖改性沥青和湿法全再生沥青混合料及其制备方法。特立尼达湖改性沥青的制备方法为：将基质沥青和特立尼达湖沥青分别预热后，按掺加比例混合，一并加热搅拌后，得到特立尼达湖改性沥青。湿法全再生沥青混合料的制备方法，包括以下步骤：按照油石比，将破碎再生料投入拌合楼中，加热干拌；再将特立尼达湖沥青改性沥青加入拌合楼，控温搅拌；最后在高温出料，得到湿法全再生沥青混合料。与现有技术相比，本发明相比较于常规的沥青混合料再生方法，使用特立尼达湖改性沥青替代再生剂，可以实现100％全再生沥青混合料，并且可以获得比再生剂加基质沥青或普通SBS改性沥青更好的高温稳定性、低温抗裂性、水稳定性和耐久性。
