Hey ... I came across this because I had to do some school work ...
The vast majority of refined bitumen is used in construction. Not in itself an interpreted, bitumen's primary use is as a constituent of products used in paving and roofing applications.
Approximately 85 per cent of all the bitumen produced worldwide is used as the binder in asphalt for roads. It is also used in other paved areas such as airport runways, car parks and footways. Typically, the production of asphalt involves mixing sand, gravel and crushed rock with bitumen which acts as the binding agent. Other materials, such as polymers, may be added to the bitumen to alter its properties according to the application for which the asphalt is ultimately intended.
A further 10 per cent of global bitumen production is used in roofing applications, where its waterproofing qualities are invaluable.
The remaining five per cent of bitumen is used mainly for sealing and insulating purposes in a variety of building materials, such as pipe coatings, carpet tile backing and paint.
Hope that helps

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.
Can use stone dust as a filler material for bituminous concrete?
yes,we can use stone dust as a filler material for bituminous concrete because of its good bonding power with the bitumen.
Name the petroleume used for surfacing of roads?
Bitumen
Why bitumen is used?
Bitumen is use as fuel.
Why do you do bitumen ductility test?
The bitumen ductility test is conducted to assess the ability of bitumen to deform without breaking or cracking at elevated temperatures. This test helps determine the suitability of bitumen for use in road construction by evaluating its flexibility and durability under different environmental conditions.
What is modified bitumen?
Modified bitumen is a type of asphalt roofing material that has polymers added to enhance its performance characteristics. These polymers can improve the material's durability, flexibility, and resistance to damage from weathering and extreme temperatures. Modified bitumen is commonly used in flat or low-slope roofing applications.

What types of products do Mustek produce?
Mustek manufactures a variety of packed bitumen products. Their bitumen products are produced at the Europoort refinery in Rotterdam, Germany. They produce 3 types of bitumen: penetration bitumen,oxidized bitumen, and hard bitumen.
What is another name for bitumen?
Typically, bitumen and "asphalt" are interchangeable.
What is cut-back bitumen?
Cut-back bitumen is a type of bitumen (asphalt) that has been diluted or cut back with a volatile solvent or oil, making it easier to work with at lower temperatures. The solvent evaporates after application, leaving behind a solid bituminous material. Cut-back bitumen is commonly used in road construction and maintenance for surface treatments and prime coating.

Does bitumen contain benzene?
Bitumen itself does not contain benzene. However, during industrial processes involving bitumen, there is a potential for generation of benzene as a byproduct due to high temperatures and processes like thermal cracking may lead to its formation. Therefore, precautions should be taken to minimize benzene exposure during bitumen handling and use.
What is bitumen pitch?
bitumen pitch means road surface
