Regeneration system and method for staged heating and regeneration of asphalt mixture
The invention discloses a regeneration system and method for graded heating of a regenerated asphalt mixture, and the regeneration method comprises the following steps: carrying out fine separation on the crushed and screened regenerated asphalt mixture to obtain a regenerated asphalt mixed fine material and a regenerated asphalt mixed coarse material; respectively heating the regenerated asphalt mixed fine material and the regenerated asphalt mixed coarse material, so that the performance of asphalt in the regenerated asphalt mixed fine material is recovered; respectively and sequentially weighing, mixing and stirring the heated regenerated asphalt mixed fine material and the heated regenerated asphalt mixed coarse material; and adding the aggregate, the powder, the asphalt and the regenerant into the regenerated asphalt mixed fine material and the regenerated asphalt mixed coarse material which are mixed and stirred, and uniformly stirring to obtain the new asphalt mixture. According to the invention, the problems of serious aging, explosion, ignition, low addition proportion and the like of the regenerated asphalt mixture caused by the original process are solved, the performance of the regenerated asphalt mixture is greatly improved, no asphalt blue smoke is generated, and the purposes of energy conservation, emission reduction, quality improvement and increment are achieved.
本发明公开了一种分级加热再生沥青混合料的再生系统及方法，再生方法包括以下步骤：对破碎筛选后的再生沥青混合料进行精细分，得到再生沥青混合细料和再生沥青混合粗料；分别对再生沥青混合细料和再生沥青混合粗料进行加热，使再生沥青混合细料中的沥青的性能得到恢复；分别对加热后的再生沥青混合细料和再生沥青混合粗料依次进行称量、混合搅拌；向混合搅拌后的再生沥青混合细料和再生沥青混合粗料加入骨料、粉料、沥青、再生剂，搅拌均匀后得到新的沥青混合料。本发明解决了原有工艺造成的再生沥青混合料老化严重、爆炸、着火、添加比例低等问题，沥青再生混合料性能大幅提升，且无沥青蓝烟产生，达到节能、减排、提质增量的目的。
