Straight run bitumen - obtained after the final stage of distillation of crude oil of a suitable type. Normal grades used - 50 pen (hard) to 300 pen (soft). Cut-back bitumen - bitumen whose viscosity has been reduced by the addition of a suitable volatile dilutant or flux. Normal grades used - 50, 100, 200 secs.
Any of a group of solid and semi-solid hydrocarbons that can be converted into liquid form by heating. Bitumens can be refined to produce such commercial products as gasoline, fuel oil, and asphalt.

A generic term for various amorphous, semi-solid mixtures of hydrocarbons derived from coal or petroleum. (Also ASPHALT, COAL TAR.)
is a viscous liquid, or a solid, which consists largely of hydrocarbons and their derivatives. It softens gradually on volatile. It occurs naturally as bitumen and, in conjunction with mineral matter, as asphalt. It is also produced as a by-product of petroleum refining. It is used as a water-proofing and binding agent.
Can be used as an adhesive under pavers. Made from a combination of asphalts and neoprene.
Any of various mixtures of hydrocarbons (as tar) often together with their nonmetallic derivatives that occur naturally or are obtained as residues after heat-refining natural substances (as petroleum); specifically : such a mixture soluble in carbon disulfide.
Any of various mixtures of hydrocarbons occurring naturally or obtained through the distillation of coal or petroleum. (See Coat Tar Pitch and Asphalt).
Bitumens are mixtures of hydrocarbons of natural or pyrogeneous origin; or combinations of both, frequently accompanied by their non metallic derivatives, which may be gaseous, liquid, or solid, and which are completely soluble in carbon disulfide. In the roofing industry the word covers both asphalt and coal tar pitch. French (Bitume)
The generic term for an amorphous, semi-solid mixture of complex hydrocarbons derived from coal-tar pitch or asphalt.
The molasses-like substance that comprises up to 18 per cent of oil sands. Bitumen, in its raw state, is black, asphalt-like oil. It requires upgrading or blending to make it transportable by pipeline and usable by conventional refineries.
Sealed road as opposed to a dirt road
Heavy oil or petroleum in semi-solid or solid forms. Bitumen generally has a density of less than 10 degrees API.
A general geological term for various solid and semi-solid hydrocarbons.
can mean either a paved (sealed) road or the black substance (usually asphalt) used to pave (seal) the road
Black, sticky substance, related to asphalt. Used in sealants, mineral felts and damp-proof courses.
a non-volatile, black or brown substance derived from refinery processes; can be viscous or solid depending on its temperature; has waterproofing and adhesive properties
an extremely heavy semi-solid product of oil refining made up of heavy hydrocarbons. It is used for road-building and roofing.
A generic term used for either asphalt or coal tar pitch.
Solid, or semi solid viscous hydrocarbon with a colloidal structure, brown to black in colour, obtained as a residue in distillation of crude oil by vacuum distillation of oil residues from atmospheric distillation. Bitumen is used mainly in road construction and i salso known as asphalt.
Crude oil in semi-solid or solid forms.
The bottom product of crude oil vacuum distillation; solid or semi-solid at room temperature.
The bottom product of crude oil vacuum distillation. A black or dark brown solid or semi-solid organic compound that gradually softens and turns into liquid when heated.
a black, tarry substance that occurs as an abundant natural product in many places, such as on the shores of the Dead Sea and the Caspian Sea; used in cements, as in the construction of coffins
An asphaltic hydrocarbon, usually in semi-liquid state. Used for patching of other asphaltic materials.
A product of the oil refinery process. Bitumen is usually stored at approximately 150°C to maintain it in a liquid form. Used in asphalt and spray seal applications.
Also called asphalt or tar, bitumen is the brown or black viscous residue from the vacuum distillation of crude petroleum. It also occurs in nature as asphalt "lakes" and "tar sands." It consists of high molecular weight hydrocarbons and minor amounts of sulfur and nitrogen compounds.
A highly viscous oil which is too thick to flow in its native state and which cannot be produced without altering its viscosity. The density of bitumen is generally less than 10 degrees API.
