Binder performance grade. This gives the temperature range in which the asphalt cement that binds the aggregate particles together is expected to perform well. For example, under this grading system a binder with a performance grade of PG 58-34 is designed for use between -34 and 58 °C.

Mix design procedures for recycled asphalt pavements require the selection of asphalt binder or recycling agent. This research project was undertaken to develop a procedure for selecting the performance grade (PG) of asphalt binder based on the Superpave PG grading system.

Superpave represents an improved system for specifying asphalt binders and mineral aggregates, developing asphalt mixture design, and analyzing and establishing pavement performance prediction. The system includes an asphalt binder specification, a hot-mix asphalt (HMA) design and analysis system, and computer software that integrates the

Oct 11,  · asphalt binders from different sources and with different performance grades (PG) needs to be well understood. Appropriate methods for extracting aged binder from reclaimed asphalt materials are still being developed; these development efforts are focused on reducing the effects of extraction solvents on the properties of recovered binders.
