The Guvnor Group is planning to invest in the Perth Amboy asphalt refinery and storage facility in New Jersey, which has been shut sincereports Bloomberg. The chart below shows the increasing fleet of ships from the two trading houses carrying bitumen. Its Singapore-based unit, Puma Energy has added four new bitumen vessels, taking the total number of vessels to 11, which cater to the Asian markets. Vitol, the largest independent oil-trading house teamed up with U. Trucks, trains, and barges have been used traditionally to transport bitumen from refineries to local consumers however, a drop in supply from the aging refineries in the U. Along with roofing, polymer modified bitumen PMBwhich is used as a chemical additive and adhesive, will witness rapid growth compared to other forms of bitumen. Waterproofing of roofing and building construction was the second major consumer of bitumen in Increased construction of homes to cater for the growing population is likely to add to the bitumen demand in the future. A surge in road construction activity in Asia will propel growth for the product going forward. 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.Bitumen is a semi-solid form of petroleum, which is used to make asphalt for roads, waterproofing for roofs, insulation, and adhesives.Д«itumen is used mainly in road manufacturing. Other examples of this confusion include the La Brea Tar Pits and the Canadian oil sands, both of which actually contain natural bitumen rather than tar.

However, since the s, when natural gas succeeded town gas, asphalt has completely overtaken the use of coal tar in these applications. 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. 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. Asphalt may be confused with coal tar, which is a visually similar black, thermoplastic material produced by the destructive distillation of coal. It is commonly modelled as a colloid, with asphaltenes as the dispersed phase and maltenes as the continuous phase. The substance is soluble in carbon disulfide. The naphthene aromatics and polar aromatics are typically the majority components. Asphaltenes, consisting of high molecular weight phenols and heterocyclic compounds. Saturated hydrocarbons the percentage of saturated compounds in asphalt correlates with its softening point. Polar aromatics, consisting of high molecular weight phenols and carboxylic acids produced by partial oxidation of the material. Naphthene aromatics naphthaleneconsisting of partially hydrogenated polycyclic aromatic compounds.

The components of asphalt include four main classes of compounds. Common colloquial usage often refers to various forms of asphalt as 'tar', as in the name of the La Brea Tar Pits. Outside the United States, the product is often called 'bitumen', and geologists worldwide often prefer the term for the naturally occurring variety.

In American English, 'asphalt' or 'asphalt cement' is commonly used for a refined residue from the distillation process of selected crude oils. The terms 'asphalt' and 'bitumen' are often used interchangeably to mean both natural and manufactured forms of the substance. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. Before the 20th century, the term asphaltum was also used. It may be found in natural deposits or may be a refined product, and is classed as a pitch. It is a sticky, black, and highly viscous liquid or semi-solid form of petroleum.
