Abstract:

The current performance grading (PG) specification for asphalt binders is based primarily on the study of unmodified asphalt binders. Over the years, experience has proven that the PG grading system, while good for ensuring overall quality, fails in some cases to predict rutting and cracking performance, particularly for modified binders. Recent studies show some mixes with softer binders used outside of Texas have both good rutting and cracking performance. However, the current binder PG system fails to justify/identify this phenomenon. It is necessary to improve the current asphalt grading system and recommend associated specification limits, especially for modified binders.
