摘要
为了进行不同类型改性沥青的抗老化性能对比,在以代表高温性能的针入度指标基础上,研究了相同等级针入度下的不同类型改性沥青在老化过程中针入度及其他指标的变化情况,分析了不同类型改性沥青抗老化性能的微观机理。研究认为不同类型改性沥青的抗老化性能均好于基质沥青。
In order to compare the anti-aging performance of different modified asphalts,based on the same penetration grade,the penetration,ductility,softening point and 135 ℃ viscosity of four different modified asphalts in the aging process have been researched,and the test results have also been discussed by the micro-mechanism. The research has demonstrated that the anti-aging performance of the modified asphalt is better than that of the original asphalt.
