沥青老化再生的实验路径研究

Study on the Experimental Path about Asphalt Aging and Regeneration

沥青路面是现阶段应用最广泛的路面形式,随着使用年限的增长路面上沥青材料发生老化后使得沥青路面的路用性能降低,这样沥青路面的再生技术应运而生。通过对比不同老化方法和不同的老化时间得到的沥青残留物的各种指标与实际的废旧沥青的各种指标,找到方便准确的适用于实验研究的老化方法,然后通过对比不同的再生方法,寻找到用于实验室研究的沥青再生方法,从而找到适用于实验研究的老化再生路径。

Asphalt pavement is most widely used at present stage. With the increase of usage years, the road performance of as- phalt pavement reduced due to asphalt aging. Therefore, asphalt roadbed regeneration technology arises at the historic moment. By comparing various indicators of asphalt residues with different aging methods and different aging time with actual indicators, the con- venient and accurate method which is suitable for the experimental study was identified. By comparing the different regeneration meth- ods, the asphalt regeneration methods for laboratory research was identified. Finally, the most suitable path for asphalt aging and re- generation experiment was obtained.
