Asphalt binderPG gradingPenetrationDSRBBRPerformancePremature rutting due to high temperatures and heavy loads has been a major distress on flexible pavements in Pakistan. One of the main causes of this early rutting is the available asphalt binders, which are still graded by using penetration grading...

The results indicated that the simplifying assumptions in the current Superpave specification (AASHTO MP1, "Standard Specifications for Performance Graded Asphalt Binder") limit its applicability to the majority of the modified binders tested. Moreover, the results indicated that many modified binders ...
