摘要
结合对 SBS改性沥青的性能特点及与非改性沥青性能的差异分析 ,总结了以路用性能为基础的 Su-perpave结合料规范的优点与不足 ,讨论了欧洲沥青技术标准最新草案的组成与特点 ,建议在目前情况下对 SBS改性沥青的质量控制与检测以及路用性能评价分别采用的 2套指标与方法 。
The rheological and mechanical properties of SBS modified bitumen are characterized with the comparison to conventional bitumen binders. Then the advantage and limitation of Superpave binder specification are summarized accordingly. The latest draft of CEN bitumen standard is introduced and viewed. At last, two sets of test methods and criteria for quality control and performance evaluation of SBS modified bitumen are recommended respectively based on the above analysis. Mix test has been recognized as a very efficient way to evaluate and compare the performance of binders.
