道路沥青在使用后将会发生老化现象，老化后沥青的组分发生了改变，在性能上表现为软化点上升，针入度降低，延度降低等。文章通过对老化沥青组分组成进行分析，通过改变老化沥青组分达到沥青再生的目的，研究表明通过掺加沥青和再生剂来进行复合再生要比单纯的采用一种办法再生具有更好的效果。再生后的沥青三大指标符合路用沥青的使用标准，完全可以用于铺筑新道路的使用，甚至可以通过添加改性剂达到改性沥青的标准。

The aged asphalt＇ component has had the change, in the performance the performance is the softening point rise, the penetration reduces, the ductility reduces and so on. The paper through to gets older component compositions and so on asphalt to carry on the analysis, achieves the asphalt regeneration through the change aging asphalt component the goal. At the same time, through two method＇s compound regeneration, displays a better effect.
