摘要
通过对两种基质沥青进行不同温度及不同速率下的延度试验 ,找出它们的流变特性 ,并从微观上进行分析 ,最后与路用性能相联系。又通过 TFOT试验找出流变特性与耐老化性之间的关系。最后得出 :沥青的流变特性可通过延度试验来表征 ,它能较好地反映沥青的路用性能。
Ductility test for two different kinds of asphalt was made at different temperature and velocity, in which the rheological property was obtained and analyzed. In addition, the relationship between rheological property and durability was also obtained from the TFOT aging test. It is shown that the paving performance can be reflected by the rheological property of the asphalt, which can be characterized by the ductility test.
