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
