The components of asphalt include four main classes of compounds: Naphthene aromatics naphthaleneconsisting 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.

It is commonly modelled as a colloidwith asphaltenes as the dispersed phase and maltenes as the continuous phase. During the early and midth century, when town gas was produced, coal tar was a readily available byproduct and extensively used as the binder for road aggregates. The addition of coal tar to macadam roads led to the word " tarmac ", which is now used in common parlance to refer to road-making materials.

However, since the s, when natural gas succeeded town gas, asphalt has completely overtaken the use of coal tar in these applications. Other examples of this confusion include the La Brea Tar Pits and the Canadian oil sandsboth of which actually contain natural Essays about oil drilling rather than tar.

Additives, mixtures and contaminants[ edit ] For economic and other reasons, asphalt is sometimes sold combined with other materials, often without being labeled as anything other than simply "asphalt.

It contains the various non-refined elements and compounds in recycled engine oil, leftover from the re-refining process—both additives to the original oil, and materials accumulating from its circulation in the engine typically iron and copper.

Some research has indicated a correlation between Essays about oil drilling contamination of asphalt and poorer-performing pavement. Naturally occurring deposits of bitumen are formed from the remains of ancient, microscopic algae diatoms and other once-living things.

These remains were deposited in the mud on the bottom of the ocean or lake where the organisms lived.

Bitumen also occurs in unconsolidated sandstones known as "oil sands" in AlbertaCanada, and the similar "tar sands" in UtahUS.

These bituminous sands contain billion barrels Although historically it was used without refining to pave roads, nearly all of the output is now used as raw material for oil refineries in Canada and the United States. Of the Alberta deposits, only parts of the Athabasca oil sands are shallow enough to be suitable for surface mining.

An example of this is within the Uinta Basin of Utahin the US, where there is a swarm of laterally and vertically extensive veins composed of a solid hydrocarbon termed Gilsonite. These veins formed by the polymerization and solidification of hydrocarbons that were mobilized from the deeper oil shales of the Green River Formation during burial and diagenesis.

Due to pressure from the rising of the Rocky Mountains in southwestern Alberta, 80 to 55 million years ago, the oil was driven northeast hundreds of kilometres and trapped into underground sand deposits left behind by ancient river beds and ocean beaches, thus forming the oil sands.

In the ancient Middle East, the Sumerians used natural bitumen deposits for mortar between bricks and stones, to cement parts of carvings, such as eyes, into place, for ship caulkingand for waterproofing.

Approximately 40 AD, Dioscorides described the Dead Sea material as Judaicum bitumen, and noted other places in the region where it could be found.

It was a valuable strategic resource, the object of the first known battle for a hydrocarbon deposit—between the Seleucids and the Nabateans in BC. This was used to cover objects that needed waterproofing, [2] such as scabbards and other items.

Statuettes of household deities were also cast with this type of material in Japanand probably also in China. In North Americaarchaeological recovery has indicated bitumen was sometimes used to adhere stone projectile points to wooden shafts.

A pamphlet datedby "a certain Monsieur d'Eyrinys, states that he had discovered the existence of asphaltum in large quantities in the vicinity of Neufchatel", and that he proposed to use it in a variety of ways — "principally in the construction of air-proof granaries, and in protecting, by means of the arches, the water-courses in the city of Paris from the intrusion of dirt and filth", which at that time made the water unusable.

In the s there was a surge of interest, and asphalt became widely used "for pavements, flat roofs, and the lining of cisterns, and in England, some use of it had been made of it for similar purposes".

William Salmon's Polygraphice provides a recipe for varnish used in etching, consisting of three ounces of virgin wax, two ounces of masticand one ounce of asphaltum. Lamb Phipson writes that his father, Samuel Ryland Phipson, a friend of Claridge, was also "instrumental in introducing the asphalte pavement in ".

Inextensions for the patent and for both patents were sought by the trustees of a company previously formed by Claridge. For example, asphalt could also be used for flooring, damp proofing in buildings, and for waterproofing of various types of pools and baths, both of which were also proliferating in the 19th century.

And numerous patents were granted in France, with similar numbers of patent applications being denied in England due to their similarity to each other. In England, "Claridge's was the type most used in the s and 50s". All three groups used the substance as an adhesive.

It is found on many different artifacts of tools and ceremonial items. For example, it was used on rattles to adhere gourds or turtle shells to rattle handles. It was also used in decorations.

Small round shell beads were often set in asphaltum to provide decorations. It was used as a sealant on baskets to make them watertight for carrying water, possibly poisoning those who drank the water. Asphalt was first used to pave streets in the s. At first naturally occurring "bituminous rock" was used, such as at Ritchie Mines in Macfarlan in Ritchie County, West Virginia from to Inasphalt-based paving was used to pave Pennsylvania Avenue in Washington DC, in time for the celebration of the national centennial.IS THIS THE START OF RUNAWAY GLOBAL WARMING?
