研究了沥青针入度、60℃动力黏度、软化点、当量软化点与车辙因子G*/sinδ之间的关系以及针入度与蠕变劲度S之间的关系。结果表明:针入度、软化点和当量软化点的对数值与车辙因子G*/sinδ的对数值之间存在很好的线性相关关系;针入度对数值与蠕变劲度S对数值之间存在较好的线性相关关系;60℃动力黏度与车辙因子G*/sinδ之间存在很好的线性相关关系。针对南美高硫原油生产的沥青,针入度与G*/sinδ之间的关联关系具有很好的适用性。
The relationship between penetration rate of asphalt, dynamic viscosity at 60 ℃, softening point, equivalent softening point and rutting factor G * / sinδ and the relationship between penetration and creep stiffness S were studied. The results show that there is a good linear relationship between the logarithm of penetration, softening point and equivalent softening point and the logarithm of rutting factor G * / sinδ. The logarithm of penetration and the logarithm of creep stiffness S There is a good linear relationship between the kinematic viscosity at 60 ℃ and the rutting factor G * / sin δ. Targeting the asphalt produced in South American high-sulfur crude oil, the correlation between penetration and G * / sinδ has good applicability.
