Bitumen Bitumen is also frequently called tar or pitch—though, properly speaking, tar is a byproduct of the carbonization of coal and pitch is actually obtained from the distillation of coal tar. Bitumen is defined by the U.S. Geological Survey as an extra-heavy oil with an API gravity less than 10° and a viscosity greater than 10,000 centipoise.

Modified Bitumen Roofing Leaks in modified bitumen roofs are difficult to isolate and a seamless roof coating system is a cost effective solution. The surfacing of the sheets is also a maintenance concern. Modified Bitumen sheets are not as sensitive to ultraviolet light as built up roofs but there is still degradation.

FAQs What is the difference between bitumen and coal tar (or tar sands)? Bitumen and coal tar, or tar as it is commonly known, are two very different materials. Firstly, they are produced in different ways: bitumen is distilled from crude oil, using a number of different processes to produce bitumen products with special characteristics.

Oil sands Oil sands are either loose sands or partially consolidated sandstone containing a naturally occurring mixture of sand, clay, and water, saturated with a dense and extremely viscous form of petroleum technically referred to as bitumen (or colloquially tar due to its similar appearance, odour, and colour).he Athabasca oil sands are more or less centered around the remote northern city of Fort McMurray. They are by far the largest deposit of bitumen in Canada, probably containing over 150 billion cubic metres (900 billion barrels) of oil in place.

- Bitumen is an oil based substance. It is a semi-solid hydrocarbon product produced by removing the lighter fractions (such as liquid petroleum gas, petrol and diesel) from heavy crude oil during the refining process. As such, it is correctly known as refined bitumen. In North America, bitumen is commonly known as “asphalt cement” or “asphalt”. While elsewhere, “asphalt” is the term used for a mixture of small stones, sand, filler and bitumen, which is used as a road paving material. The asphalt mixture contains approximately 5% bitumen.

Modified Bitumen Roofing Modified Bitumen Roofing. Asphalt degradation is a growing concern. UV-rays oxidize the surface of the asphalt and produces a chalk-like residue. As plasticizers leach out of the asphalt, a modified bitumen or mod bit roof becomes brittle. Cracking and alligatoring inevitably follows, allowing water to penetrate the system causing blisters, and cracks. Seam failure inevitably follows causing leaks.

What Are Tar Sands? Tar sands are an increasingly common—but expensive and dirty—source of oil. Tar sands (also known as oil sands) are a mixture of mostly sand, clay, water, and a thick, molasses-like substance called bitumen. Bitumen is made of hydrocarbons—the same molecules in liquid oil—and is used to produce gasoline and other petroleum products.

What is Crude Oil? A Detailed Explanation on this Essential Fossil Fuel Oil Sands. Oil can also be extracted from oil sands, often called tar sands. Oils sands are typically sand or clay mixed with water and a very viscous form of crude oil known as bitumen. The extraction process for oil sands is quite different from drilling due to the high viscosity of this extra-heavy oil.

- By K. Kris Hirst. Bitumen is a black, oily, viscous material that is a naturally-occurring organic byproduct of decomposed organic materials.he earliest reed boat discovered yet was coated with bitumen, at the site of H3 at As-Sabiyah, about 5000 BC. And, one of the myths of the Mesopotamian Sargon the Great of Akkad was that as an infant he floated in a bitumen-coated reed basket down the Euphrates River.

What is Asphalt Pavement? Liquid asphalt – a sticky black substance – is used as the binding material in asphalt pavements. It is viscous in nature and can also be found in semi solid forms. Another common term for asphalt is bitumen. The pavement – once mixed – consists of 90 to 95% aggregate and sand, and 5 to 10% asphalt or bitumen.Asphalt pavements high viscosity binds the materials that make up asphalt, while allowing it to simultaneously retain flexibility.nother common term for asphalt is bitumen.

Modified Bitumen Roofing Bitumen is reinforced with fiberglass or polyester fiber matting in order to increase durability and strength. The two most common types are SBS and APP. The use of SBS (styrene-butadiene-styrene) increases the flexibility of the membrane and allows it to have stronger expansion and contraction capabilities. APP (attactic polypropylene) increases the aging ability of the roof system.

- Reduced availability of light conventional crudes in the future will create demand for new crude sources that will necessitate refinery configuration changes. The production of heavy crudes, synthetic crudes, and bitumen blends is growing, and the supply of bitumen-derived crudes is expected to reach almost three million barrels per day by the year 20151. A plethora of synthetic crudes and bitumen blends have become available, all of which pose different challenges for today’s refiners. Some crudes are both higher in contaminant levels and have a composition that makes them more difficult to upgrade. Coupled with the demand for increased production of
