| 摘 要： | 采用薄膜烘箱（TFOT）在不同时间、不同温度下对五种代表性的沥青进行老化。通过对老化前后沥青的质量变化、针入度比、粘度比、沥青质含量的比较得到了五种沥青在不同条件下性质变化规律，提出了用质量损失表征抗老化性能和用延长薄膜烘箱试验时间模拟长期老化的不适宜性。

| Abstract: | Five typical asphalts were aged by Thin Film Oven Test(TFOT)by different time at the same temperature and different temperature with the same time By comparing the mass loss,penetration ratio,viscosity ratio,asphaltene of the aged asphalt with their base asphalt,the aging regulation of five asphalt was found The results suggest that it is not proper to value anti aging properties of asphalt with mass loss and to imitate the long time aging of asphalt by prolonging test time of TFOT |
