摘要
沥青薄膜加热试验(TFOT)和沥青旋转薄膜加热试验(RTFOT)是用于评价沥青老化性能的两种试验方法。二者是同一性质的试验,规范规定可以相互代替。但二者的试验条件不同,通过试验并结合相关理论分析了两种不同方法之间的联系以及对沥青的老化程度的差异。
TFOT and RTFOT are two different test methods of appraising asphalt aging performance, Both are the same test in nature, they can substitute each other according to the criterion. However, the test conditions of the two are different. Based on the relative theory and experiments, the relation and difference for asphalt aging extent between the two different methods are analyzed.
