Bitumen sands are a natural sand or sandstone deposit which at some stage had been saturated with hydrocarbons. But which at some later stage had been exposed to conditions such that only the heavy (or long-chain) molecules remain. Or at least from which the lighter liquids and volatiles have disappeared.
Actually a very common form of hydrocarbon deposit.
It means eyes, black like coal. Bitumen is the British term for coal.

Bitumen Bi*tu"men
bitumen pitch means road surface
'asphalt' refers to a mixture of mineral aggregate and bitumen (bitumen)is the black liquid which is extracted from the crude oil....
ASTM D6847 gives the procedure for it
cut black bitumen needs a solvent to dilute it whereas emulsion doesn't.
Cut-back bitumen uses solvent as the mixing medium where in Emulsion uses water to dilute bitumen for the purpose of tack-coating / road works
Bitumen is used in place of coal tar in making roads.
