Performance Grade Bitumen is graded based on pavement temperatures. In Super-pave grading system,
binders are classified according to their Performance in extreme hot and cold temperatures and called as Performance
Grade Bitumen. The main purpose of grading and selecting asphalt binder using the Performance Grade system is to
make certain that the binder has the appropriate properties for environmental conditions in the field. Performance
Grade asphalt binders are selected to meet expected climatic conditions as well as traffic speed and volume
adjustments. Therefore, the Performance Grade system uses a common set of tests to measure physical properties of
the binder that can be directly related to field performance of the pavement at its service temperatures by engineering
principles. Performance grade bitumen generally are mostly applied in paving constructions and reconstructions,
sealing of edges, crack sealing, spray applications for the bridge deck, and in both dense-graded and open-graded Hot
Mix Asphalt (HMA). PG grades that are well-structured against thermal cracking are PG 58-34, PG 64-22, PG 64-28,
and PG 76-22. PG grades that are resistant to rutting are PG 70-22, PG 70-28, PG 76-28, and PG 82-22.PG 58-28 is
specifically used in very cold regions.
