基于不同老化方式的沥青评价指标研究

The research based on the different ways of aging asphalt evaluation parameters

为了研究不同老化方式对沥青性能的影响,选用TFO老化和PAV老化,采用的沥青为中海70号基质沥青和SBS改性沥青,通过对沥青的老化试验,得到老化后的常规指标。

In order to study the effect of different aging methods on asphalt performance,TFO and PAV are used to simulate the Short-term aging and long-term aging of the matrix asphalt and SBS modified asphalt.then we can get the routine parameter.
