There are different types of bitumen in Iran based on the performance grade (PG) which were categorized since four years ago and are produced depending on weather conditions in various regions, reported Fars News Agency.
Iranian researchers have now succeeded in the production of a new type of bitumen, based on normal, heavy, very heavy and extra heavy traffic, which also enjoy the quality of being produced for different weather conditions.
