einer Strasse wird aber heute kein Tropfen Teer ( mehr ) verwendet.
Bitumen und Teer sind zwei völlig verschiedene Stoffe, auch wenn beide braunschwarz und dickflüssig sind.
Bitumen ist der Rückstand nach Abtrennung der leichter flüchtigen Anteile ( Benzin, Kerosin, Schweröl, etc ) bei der Destillation von Erdöl.

Bitumen and tar are two completely different materials, even though they ’ re both black-brown and viscous.
Bitumen is the residue from the separation of more highly volatile contents ( gasoline, kerosene, heavy oil ) during the distillation of petroleum.
