Bitumen is a black substance that is in the form of a paste and can have many applications, especially in moisture insulation and asphalt construction. In general, there are two types of bitumen: natural bitumen (Gilsonite) and refinery bitumen, which have many similarities but also have differences. Basically, natural bitumen is obtained in a ready form through mineral extraction, and refinery bitumen is obtained in the process of oil processing.
