【Abstract】 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.更多还原
