Performance Grade

PG system is a method of measuring asphalt binder performance; In a Super-pave grading system, binders are classified according to their performance in extreme hot and cold temperatures and called Performance Grade Bitumen.
The main purpose of grading and selecting asphalt binder using the Performance Grade system is to ensure 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 the physical properties of the binder that can be directly related to the field performance of the pavement at its service temperatures by engineering principles.

BHP is able to supply blow bitumen PG grades:

High temperature degrees of efficiency low temperature degrees of efficiency
PG 46 -34,-40,-46
PG 52 -10, -16, -22, -28,-34, -40, -46
PG 58 -10, -16,-22, -28, -34, -40
PG 64 -10, -16, -22, -28,-34, -40
PG 70 -10, -16,-22, -28,-34, -40
