bitumen / bɪtuːmən /
Množina reči bitumen je bitumens.
ETYM Latin bitumen: cf. French bitume. Related to Béton.
Any of various naturally occurring impure mixtures of hydrocarbons.
Mineral pitch; several partly oxygenated hydrocarbons; asphalt; pigment obtained from asphalt.
Impure mixture of hydrocarbons, including such deposits as petroleum, asphalt, and natural gas, although sometimes the term is restricted to a soft kind of pitch resembling asphalt.
Solid bitumen may have arisen as a residue from the evaporation of petroleum. If evaporation took place from a pool or lake of petroleum, the residue might form a pitch or asphalt lake, such as Pitch Lake in Trinidad. Bitumen was used in ancient times as a mortar, and by the Egyptians for embalming.
