| 摘 要： | 为了研究基质沥青与改性沥青老化性质的差异,通过薄膜烘箱试验以及压力老化试验分别模拟沥青不同时间的短期老化和长期老化,然后通过DSR试验得到原样沥青以及不同老化程度沥青的流变数据,分析基质沥青与改性沥青的老化性质和沥青的低温玻璃化转变情况、模量大小、黏弹性组成等方面的信息,以及在工程使用中的实际意义。

| Abstract: | In order to research the difference of aging properties between matrix asphalt and modified asphalt , short - term aging by using TFOT and various hours aging by using PAV were conducted, then through DSR test the rheological data of the original asphalt and different aged degree asphalt was got. The aging properties, glass transition at low temperature, the modulus and viscoelastic composition information of the matrix asphalt and modified asphalt could be well analyzed. The result provided guidance to the project practice. |
