ASPHALT /ˈæsˌfɔːlt, -ˌfɑːlt/ , also known as BITUMEN /ˈbɪtʃəmᵻn, bᵻˈtuːmᵻn/ , is a sticky, black, and highly viscous liquid or semi-solid form of petroleum . It may be found in natural deposits or may be a refined product, and is classed as a pitch . Before the 20th century, the term ASPHALTUM was also used. The word is derived from the Ancient Greek ἄσφαλτος _ásphaltos_.
The primary use (70%) of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete . Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs.
The terms "asphalt" and "bitumen" are often used interchangeably to mean both natural and manufactured forms of the substance. In American English , "asphalt" (or "asphalt cement") is commonly used for a refined residue from the distillation process of selected crude oils. Outside the United States, the product is often called "bitumen", and geologists worldwide often prefer the term for the naturally occurring variety. Common colloquial usage often refers to various forms of asphalt as "tar ", as in the name of the La Brea Tar Pits .
Naturally occurring asphalt is sometimes specified by the term "crude bitumen". Its viscosity is similar to that of cold molasses while the material obtained from the fractional distillation of crude oil boiling at 525 °C (977 °F) is sometimes referred to as "refined bitumen". The Canadian province of Alberta has most of the world's reserves of natural asphalt, covering 142,000 square kilometres (55,000 sq mi), an area larger than England .

The word "asphalt" is derived from the late Middle English, in turn from French _asphalte_, based on Late Latin _asphalton_, _asphaltum_, which is the latinisation of the Greek ἄσφαλτος (_ásphaltos_, _ásphalton_), a word meaning "asphalt/bitumen/pitch ", which perhaps derives from ἀ-, "without" and σφάλλω (_sfallō_), "make fall". The first use of asphalt by the ancients was in the nature of a cement for securing or joining together various objects, and it thus seems likely that the name itself was expressive of this application. Specifically, Herodotus mentioned that bitumen was brought to Babylon to build its gigantic fortification wall. From the Greek, the word passed into late Latin, and thence into French (_asphalte_) and English ("asphaltum" and "asphalt"). In French, the term _asphalte_ is used for naturally occurring asphalt-soaked limestone deposits, and for specialised manufactured products with fewer voids or greater bitumen content than the "asphaltic concrete" used to pave roads.
The expression "bitumen" originated in the Sanskrit words _jatu_, meaning "pitch," and _jatu-krit_, meaning "pitch creating" or "pitch producing" (referring to coniferous or resinous trees). The Latin equivalent is claimed by some to be originally _gwitu-men_ (pertaining to pitch), and by others, _pixtumens_ (exuding or bubbling pitch), which was subsequently shortened to _bitumen_, thence passing via French into English. From the same root is derived the Anglo-Saxon word _cwidu_ (mastix), the German word _Kitt_ (cement or mastic) and the old Norse word _kvada_.
In British English , "bitumen" is used instead of "asphalt." The word "asphalt" is instead used to refer to asphalt concrete , a mixture of construction aggregate and asphalt itself (also called "tarmac " in common parlance). Bitumen mixed with clay was usually called "asphaltum", but the term is less commonly used today.
In Australian English , "bitumen" is often used as the generic term for road surfaces.
In American English , "asphalt" is equivalent to the British "bitumen". However, "asphalt" is also commonly used as a shortened form of "asphalt concrete " (therefore equivalent to the British "asphalt" or "tarmac").
In Canadian English , the word "bitumen" is used to refer to the vast Canadian deposits of extremely heavy crude oil , while "asphalt" is used for the oil refinery product. Diluted bitumen (diluted with naphtha to make it flow in pipelines) is known as "dilbit " in the Canadian petroleum industry, while bitumen "upgraded " to synthetic crude oil is known as "syncrude", and syncrude blended with bitumen is called "synbit".
"Bitumen" is still the preferred geological term for naturally occurring deposits of the solid or semi-solid form of petroleum. "Bituminous rock" is a form of sandstone impregnated with bitumen. The tar sands of Alberta, Canada are a similar material.
Neither of the terms "asphalt" or "bitumen" should be confused with tar or coal tars .

The components of asphalt include four main classes of compounds:
* Naphthene aromatics (naphthalene ), consisting of partially hydrogenated polycyclic aromatic compounds * Polar aromatics, consisting of high molecular weight phenols and carboxylic acids produced by partial oxidation of the material * Saturated hydrocarbons ; the percentage of saturated compounds in asphalt correlates with its softening point * Asphaltenes, consisting of high molecular weight phenols and heterocyclic compounds
The naphthene aromatics and polar aromatics are typically the majority components. Most natural bitumens also contain organosulfur compounds , resulting in an overall sulfur content of up to 4%. Nickel and vanadium are found at

Canadian "bitumen" supply is more loosely accepted as production from the Athabasca, Wabasca, Peace River and Cold Lake oil-sands deposits. The majority of the oil produced from these deposits has an API gravity of between 8° and 12° and a reservoir viscosity of over 10,000 centipoise although small volumes have higher API gravities and lower viscosities. * ^ _A_ _B_ _C_ "ST98-2015: Alberta\'s Energy Reserves 2014 and Supply/Demand Outlook 2015–2024" (PDF). _Statistical Reports (ST)_.
