Performance Grades Bitumen Supplier

Performance Grade Bitumen is a Graded Based Bitumen which is Based on its Performance at different 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. 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.

The Performance grading system defined by two numbers, which represent pavement temperatures. The first number PG 64-XX represents the High pavement temperature in degrees Celsius, while the second number PG XX-22 represents the Low pavement temperature. Notice that these numbers are pavement temperatures and not air temperatures (these pavement temperatures are estimated from air temperatures using an algorithm contained in the LTPP Bind program). All adjustments to the Performance Grading System are made in six (6) degree increments. The High temperature relates to the effects of rutting and the Low temperature relates to cold temperature and fatigue cracking.

Tiger Bitumen Company has the capability to Supply the Performance Grades Bitumen in compliance with National and International standards.
