PG 64-22

Bitumen PG 64-22 is Performance Grade (PG) Bitumen is bitumen which is graded based on its performance at different temperatures. Performance Grade (PG) bitumen cement based on two factors: traffic and pavement temperature.

Adjustments are made to the PG grade of asphalt cement based on traffic conditions and traffic volumes which are intended to enhance the design life of the pavement.

 

Application of Bitumen PG 64-22

The PG 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. It is one of the most important changes introduced in Super pave that acceptance limits are the same but have to be met at specific pavement temperature and traffic conditions.

PG 64-22 is specifically used in mild regions with very cold winter.
