In British English, 'bitumen' is often used interchangeably with both 'asphalt' and 'tar'. In American English, 'bitumen' is most commonly used in engineering jargon to explicitly include both asphalt- and tar-based materials. In Australian English, 'bitumen' is used as the generic term for road surfaces.
Bitumen is primarily used in creating asphalt for roads, and used raw as a substance to repair roads. It may also be refined into oil, but a cost-effective way of doing this has yet to be discovered.
Vessels for the heating of bitumen or bituminous compounds are a usual exclusion of public liability insurance policies.
