摘要
基于SHRP沥青路用性能规范,采用疲劳因子评价沥青结合料疲劳性能时受复数剪切模量和相位角共同影响。文章通过对7种不同沥青样品在不同试验温度下进行动态剪切流变试验,测试各沥青样品的复数剪切模量、相位角及疲劳因子,从而分析疲劳因子、复数剪切模量及相位角与疲劳性能之间的关系。
Based on the SHRP asphalt with performance specifications,using the fatigue factor evaluating fatigue performance of asphalt binder influenced by complex shear modulus and phase Angle,this article through to 7 different asphalt samples at different test temperatures for dynamic shear rheological test,the test samples of plural asphalt shear modulus and phase Angle and fatigue factor,thus analysis fatigue factor,complex shear modulus and phase Angle and the relationship between the asphalt fatigue performance.
