| 摘 要： | 根据Arrhenius方程分析了沥青在加速热老化试验条件下的临界老化时间与老化温度的关系，提出利用临界老化时间与老化温度绘制Arrhenius图，以及利用Arrhenius图预估沥青使用寿命的试验方法。采用该方法估算了所选2种沥青的使用寿命，并分析了影响沥青寿命预估的因素。采用该方法估算的沥青寿命值呵为路面寿命周期成本分析和路面养护时机的选择提供参考。

| Abstract: | The relation between critical thermal aging time and aging temperature of asphalt under accelerated aging test conditions was analyzed based on Arrhenius equation. It was pointed out to make Arrhenius chart using critical aging time and aging temperature,and to create the service life estimation method of asphalt based on Arrhenius chart. Two kinds of asphalt were select- ed for estimation of their service life by this method. The factors effecting the life estimation of asphalt were analyzed. The service l... |
