bitumen

Black paving substance

Bitumen is a thick, sticky, black or dark brown substance derived from petroleum or found naturally in deposits.

It is the binding agent in asphalt, used to pave roads and waterproof roofs.

The term is more common in British English, where Americans typically say asphalt for the finished road surface.

Workers spread hot bitumen before laying the aggregate.

In its natural form, bitumen seeps from the earth in tar pits and oil sands.
