道路废旧沥青混合料老化与再生试验研究

Study of waste asphalt mixture aging and regeneration by experiment

选取公路路面改造的废旧沥青混合料,通过破碎、筛分旧路材料,对旧沥青进行老化试验,并通过添加不同种类和不同含量的再生剂,研究老化沥青再生。使旧路面沥青性能改善到能回收再利用。

A waste asphalt mixture of pavement reconstruction was chosen. By through crushing and screening the old road material,the aging test of asphalt was operated. By adding different kinds and different content of recy- cling agent,make aged asphalt regeneration,which make old pavement asphalt that can be recovered and recycled.
