Bitumen sands are a natural sand or sandstone deposit which at some stage had been saturated with hydrocarbons. But which at some later stage had been exposed to conditions such that only the heavy (or long-chain) molecules remain. Or at least from which the lighter liquids and volatiles have disappeared.
Actually a very common form of hydrocarbon deposit.

Difference between cut-back bitumen and emulsion bitumen?
cut black bitumen needs a solvent to dilute it whereas emulsion doesn't.
Can asphalt be defined as the combination of bitumen and aggregate?
No, within the US and Poland, asphalt is synonymous with bitumen. The correct term for a mixture of bitumen and aggregates is asphalt concrete.
What is deference between cut back bitumen and bitumenemulsion?
Cutback Bitumen : Normal practice is to heat bitumen to reduce its viscosity. In some situations preference is given to use liquid binders such as cutback bitumen. In cutback bitumen suitable solvent is used to lower the viscosity of the bitumen. From the environmental point of view also cutback bitumen is preferred. The solvent from the bituminous material will evaporate and the bitumen will bind the aggregate. Cutback bitumen is used for cold weather bituminous road construction and maintenance. The distillates used for preparation of cutback bitumen are naphtha, kerosene, diesel oil, and furnace oil. There are different types of cutback bitumen like rapid curing (RC), medium curing (MC), and slow curing (SC). RC is recommended for surface dressing and patchwork. MC is recommended for premix with less quantity of fine aggregates. SC is used for premix with appreciable quantity of fine aggregates.Bitumen Emulsion : Bitumen emulsion is a liquid product in which bitumen is suspended in a finely divided condition in an aqueous medium and stabilized by suitable material. Normally cationic type emulsions are used in India. The bitumen content in the emulsion is around 60% and the remaining is water. When the emulsion is applied on the road it breaks down resulting in release of water and the mix starts to set. The time of setting depends upon the grade of bitumen. The viscosity of bituminous emulsions can be measured as per IS: 8887-1995. Three types of bituminous emulsions are available, which are Rapid setting (RS), Medium setting (MS), and Slow setting (SC). Bitumen emulsions are ideal binders for hill road construction. Where heating of bitumen or aggregates are difficult. Rapid setting emulsions are used for surface dressing work. Medium setting emulsions are preferred for premix jobs and patch repairs work. Slow setting emulsions are preferred in rainy season.
Name the petroleume used for surfacing of roads?
Bitumen
What are the heaviest fractions of crude oil used for?
Bitumen for roads.
What type of resources does tar sands come from?
Tar sands or oil sands are consist of clay, sand, water, and bitumen. Its bitumen content is extracted and separated to purify it into oil.
How are oil sands formed?
Oil sands are formed from a mixture of sand, water, clay, and bitumen - a heavy oil. Over millions of years, organic material decays and the bitumen collects in sand and silt deposits, creating oil sands. Heat and pressure further transform the bitumen into crude oil.
What are oil sands?
Oil sands are deposits of bitumen, sand, clay and water. Bitumen is a heavy, viscous oil that at room temperature is a lot like cold molasses. The bitumen must be diluted with lighter hydrocarbons before it is usable by refineries to produce gasoline and diesel fuels.
What is the Athabasca oil sands?
The Athabasca oil sands are large deposits of bitumen, a heavy and unconventional oil found in Northern Alberta, Canada. These reserves are one of the largest sources of oil in the world, but extracting and processing bitumen is resource-intensive and has environmental implications.
Can you describe what the oil sands are and how oil is taken out of them?
Hi Oil sands are also called tar sands or bituminous sand. To separate the Bitumen from the sand and form the bitumen oil, instead of steam, hydrocarbon solvents are injected into the sands. This is considered to be a better energy efficient system than using steam. It has environmental costs, and transport costs as it is thick. It has to be transported by road rather than pipe.
How is orimulsion formed?
Orimulsion is formed by blending natural bitumen, a heavy crude oil, with water and a small amount of surfactant to create a stable emulsion. The bitumen is usually extracted from tar sands or oil sands, and the resulting mixture has a high energy content that can be used as a fuel for power generation.
What is a mixture of clay and sand with bitumen could replace petroleum one day?
The mixture of clay, sand, and bitumen that you mention is normally known as tar sand, and there are large deposits of it in the Canadian province of Alberta, as well as a few other locations. The bitumen can be extracted from the mixture and can then be refined into petroleum products such as gasoline, etc. This is more expensive than using oil from oil wells, however, in a world of very high and ever increasing oil prices, the exploitation of tar sands has become economically viable.
What is the density of bitumen at different temperature ranges?
The density of bitumen can vary depending on the temperature. At 25°C, the density of bitumen is around 1,000 kg/m^3. As the temperature decreases, the density increases due to the bitumen becoming more viscous. Conversely, as the temperature increases, the density decreases as the bitumen becomes less viscous.
What does bitumen mean?

What does bitumen eyes mean in A pale-faced figure with bitumen eyes?
It means eyes, black like coal. Bitumen is the British term for coal.
What country contains large tar sands?
Canada
What are the Athabasca Tar Sands?
The Athabasca Tar Sands, also known as the Athabasca oil sands, are deposits of bitumen in Alberta, Canada. They are a major source of unconventional oil production but are controversial due to environmental concerns surrounding their extraction process, which is energy-intensive and produces high levels of greenhouse gas emissions.
