"Bitumen" redirects here. For naturally occurring bituminous sands used for petroleum production
The terms bitumen and asphalt are mostly interchangeable, except where asphalt is used as an abbreviation for asphalt concrete
The primary use 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 the carefully refined residue from the distillation process of selected crude oils. Outside the United States, the product is often called bitumen. Natural deposits terminology also sometimes uses the word bitumen,
The substance is completely soluble in carbon disulfide, and composed primarily of a mixture of highly condensed polycyclic aromatic hydrocarbons; it is most commonly modelled as a colloid, with asphaltenes as the dispersed phase and maltenes as the continuous phase (though there is some disagreement amongst chemists regarding its structure). One writer stated although a "considerable amount of work has been done on the composition of asphalt, it is exceedingly difficult to separate individual hydrocarbon in pure form",[8] and "it is almost impossible to separate and identify all the different molecules of asphalt, because the number of molecules with different chemical structure is extremely large".[9]
Most natural bitumens contain sulfur and several heavy metals, such as nickel, vanadium, lead, chromium, Mercury, arsenic, selenium, and other toxic elements.[citation needed] Bitumens can provide good preservation of plants and animal fossils.

What can peat become if compressed long enough?
this is the order from peat to coal, peat-lignite-bituminous-anthracite- the higher up the the types, the higher BTU burn you well get, as well as a cleaner burn, but it takes more energy to get it started.
How do you pronounce bituminous?
It is pronounced: bi-tum-mi-nuss with the accent on tum.try bit-you-min-us
Where can scientist find a bituminous rock?
Bituminous rock can be found in sedimentary rock formations, typically in areas where ancient swamps or marshes existed. Some common locations where scientists might find bituminous rock include coal mines, sedimentary basins, and regions with a history of coal formation.
What is a very hard rock that burns with a high heat and smoke a metamorphic rock formed from coal?
The rock you are referring to is anthracite coal, which is a type of metamorphic rock formed from coal with a high carbon content. Anthracite coal burns with a high heat and produces little smoke due to its high carbon content and low volatile matter.
Explain how aggregates are processed for the use as a Portland cement concrete ingredient or as a bituminous concrete ingredient?
Aggregates are processed for concrete or bituminous concrete by crushing and screening them to produce the desired sizes and gradation. For Portland cement concrete, the aggregates need to be clean and free from debris to ensure good bonding with the cement paste. For bituminous concrete, the aggregates are coated with bitumen to enhance adhesion and durability. Proper processing of aggregates is essential to ensure the quality and performance of the final concrete or bituminous concrete mix.

What is bituminous coal?
Bituminous coal is a type of coal that is commonly used for energy production and heating. It has a higher carbon content than lignite and sub-bituminous coal, making it a more efficient fuel source. Bituminous coal is known for its relatively high heat content and is often used in industrial processes and electricity generation.
What type of coal does Montana mine?
Montana mainly mines sub-bituminous coal. This type of coal has a lower energy content and higher moisture content compared to bituminous coal, making it less desirable for some applications.
What are the varieties of coal formed inside the earth?
wood-peat-lignite-subbituminous-bituminous-anthracite The wood is converted to anthracite (coal) through various stages. lignite, subbituminous,bituminous,anthracite are the major coal types formed these are ranked based on the presence of carbon ,hydrogen and oxygen content
What are the differences between the types of coal?
The main types of coal are anthracite, bituminous, and lignite. Anthracite is the highest rank of coal and has high carbon content, making it the cleanest burning coal. Bituminous coal has a lower carbon content and is commonly used for electricity generation. Lignite is the lowest rank of coal, with the highest moisture content and lowest carbon content, making it less energy-dense than anthracite and bituminous coal.
What is the difference between lignite and bituminous coal?
Lignite is a low-grade coal with low carbon content and high moisture content, making it less energy-dense than bituminous coal. Bituminous coal, on the other hand, has a higher carbon content and energy density, making it a more valuable and widely-used form of coal for energy production.
Which coal type is harder anthracite or bituminous?
Anthracite is harder than bituminous coal. Anthracite has a higher carbon content and lower moisture content, making it a more dense and harder coal type.
Should diesel be used as thinner in bituminous paint?
NO Do not use ANYTHING not recommended by the manufacturer.
What is the difference in peat bituminous lignite and anthracite?
Peat is an organic matter with the lowest carbon content and a precursor to coal. Bituminous coal has a higher carbon content than peat and is widely used for electricity generation. Lignite is a low-grade coal with a higher carbon content than peat but lower than bituminous coal. Anthracite is the highest grade of coal with the highest carbon content and the cleanest-burning properties.
What does bituminous coal?
Bituminous coal is a type of coal known for its high carbon content and energy value. It is widely used in electricity generation, steel production, and industrial processes due to its relatively high heat content compared to other types of coal. Bituminous coal is formed when heat and pressure are applied to organic matter over millions of years.
What are the four forms of coal?
The four forms of coal are lignite, sub-bituminous, bituminous, and anthracite. These forms differ in their carbon content and energy value, with lignite being the lowest in carbon content and anthracite being the highest.
How many forms of coal are there?
Coal is classified into four general categories, or "ranks." They range from lignite through sub-bituminous and bituminous to anthracite, reflecting the progression of individual deposits of coal to increasing heat and pressure. Anthracite coal has the highest carbon content, frequently associated with home heating. Bituminous coal is the most plentiful form of coal in the United States, and is used primarily to generate electricity and make coke for the steel industry. Sub-bituminous coal ranks below bituminous. This coal generally has a lower sulfur content than other types, which makes it attractive for use because it is cleaner burning. Lignite coal is a geologically young coal which has the lowest carbon content, 25-35 percent. Sometimes called brown coal, it is mainly used for electric power generation. Hope it helped :)
