Asphalt is a word with different meanings. In American usage asphalt, or, in full, asphalt cement, is used to mean bitumen (or bitumen binder). In the term 'rock asphalt' it defines a mineral substance that may be impregnated with bitumen or pitch. Outside America the word asphalt means a mixture of bitumen and mineral aggregates laid as a road surface.
