Abstract: Binder plays a crucial role in asphalt performance, due to which it has been given immense importance by the asphalt industry. Binder grading systems are used to characterize binders based on their physical properties. Pakistan is facing the problem of rutting in asphaltic concrete due to extreme weather conditions and heavy traffic loadings. This work aims characterization of indigenous binder based on SUPERPAVETM binder requirements. Asphalt performance grades for Pakistan were formulated on the basis of comprehensive air temperature data collection and analysis. The whole country was divided into 7 different performance grade zones on the basis of previous 20 years temperature data collected from 30 weather stations. The recommended grades are PG 76-4, PG 70-10, PG 70-4, PG 64-10, PG 64-4, PG 58-10 and PG 58-4. Also a temperature zoning map has been proposed to be implemented in Pakistan
