Epoxy asphalt regenerated mixture with large old material mixing amount as well as preparation method and test of epoxy asphalt regenerated mixture
The invention discloses a high-old-material-doping-amount epoxy asphalt regenerated mixture as well as a preparation method and test thereof, and belongs to the technical field of road engineering materials. The method comprises the following steps: carrying out pretreatment and fine grading screening on the asphalt pavement milling material (RAP); preparing epoxy resin and a curing agent into an epoxy system; adding the RAP material subjected to fine treatment into an epoxy system to prepare an epoxy asphalt regenerated mixture; curing the epoxy asphalt regenerated mixture, forming a test piece, determining the asphalt-aggregate ratio, carrying out a pavement performance test, and carrying out production through a hot mix plant regeneration process after the requirements are met; before the epoxy asphalt regenerated mixture is paved on an asphalt pavement structure layer, a wheel-sticking-free epoxy asphalt binding material is spread. According to the invention, the utilization ratio of the RAP material is greatly improved, the demand of pavement engineering on road building materials is reduced, the pavement service quality is improved, and effective emission reduction in the full life cycle of the asphalt pavement is realized.
本发明公开了一种大旧料掺量环氧沥青再生混合料及其制备方法、测试，属于道路工程材料技术领域。本方法步骤为：对沥青路面铣刨料(RAP)进行预处理和精细化分档筛分；将环氧树脂与固化剂制备形成环氧体系；将精细处理后的RAP料加入环氧体系制备形成环氧沥青再生混合料；对环氧沥青再生混合料进行养生，成型试件，确定油石比并开展路用性能测试，满足要求后通过厂拌热再生工艺进行生产；将环氧沥青再生混合料摊铺到沥青路面结构层前，撒布不粘轮环氧沥青粘结料。本发明极大提高了RAP料的利用比例，降低路面工程对筑路材料的需求，提升路面服役品质，实现沥青路面全生命周期内的有效减排。
