Asphalt also known as bitumen, is a sticky, black and highly viscous liquid whose form in the petroleum, as the hydrocarbon molecules are quite long and do not slide easily over each other. The primary used of bitumen is in road construction.

What is another name for bitumen?
Typically, bitumen and "asphalt" are interchangeable.
What is cut-back bitumen?
what is the difference between cutback bitumen, bitumen and bituminous emulsion?what conditions prevails the use of the above types?
What is modified bitumen?
Modified Bitumen it makes bitumen more power while you use it in construction area , Modified Bitumen Introduced in Eighties to combat with common pavement distress. There are about 4 different specifications based on type of modifier used similar to ASTM specifications for modified bitumen. Many Authorities advises for use of minimum 10% modified Bitumen
What is the difference between bitumen and crude oil?
'asphalt' refers to a mixture of mineral aggregate and bitumen (bitumen)is the black liquid which is extracted from the crude oil....
Which fraction of crude oil is viscous?
Crude oil is about as different as cheese. Varies a lot. color is black/brown,water white,dark green,reddish etc. it depends upon the components it hold (As lighter components it hold as lighter in color and as heaver as dark it will be) density is between 700 - 1000 kg/cum and kinematic viscosity can be anywhere between 1 and 8 cSt (centi stokes)
What are Properties of bitumen?
Bitumen is a visco elastic material. that is at room temperature it act as a semi solid. in high temperatures over 60C it acts as a Newtonian fluid or low viscosity liquid. Penetration and viscosity are the main two properties checked to categories bitumen. on the other hand flash point,fire point,solubility, ductility and softening point of the bitumen are also checked.
What is the freezing point of bitumen?
The Viscosity of Bitumen is 240 cst.
What are some examples of fluids with a high viscosity?
Bitumen/pitch/tar. Quark-gluon plasma.
How do you get soft bitumen to set at room temperature?
Bitumen is not reactive in the sense that it sets. Furthermore, it's strongly temperature sensitive ie the apperance will depend on temperature. This is perhaps one of the main properties of bitumen, along with stickiness. If its fluid (or thick) n room temperature it will stay that way. There are slow processes, chemical and physical, that will affect properties but these are slow and long term. If you want it to set, lower the temperature or choose another quality of bitumen. There are bitumens that more or less brittle at room temperature.
What is the softening point of bitumen?
"Softening point:The temperature in degrees C at which a bitumen attains a particular degree of softness with reference to test conditions prescribed by BS EN 1427 or equivalent."Refined Bitumen Association: Glossary of Termswww.bitumenuk.com/bitumen-glossaryofterms.asp [Accessed 2009]
What fluids have the highest viscosity?
lots of ones like; Tar, Bitumen... these are fluids that are low on the fractional distillation tank....
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.
What is the density of bitumen at different temperature ranges?
See: Properties of Oil Sands and Bitumen in Athabasca 2006 Fig 7 http://www.cspg.org/conventions/abstracts/2006abstracts/135S0131.pdf
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.
Difference between tar and bitumen?
tar - obtained by destructive distillation of coal , it is less viscous as it is boiled with volatile fluids like kerosene bitumen - obtained by fractional distillation of crude oil , has more viscosity than tar , soluble in carbon disulphide and has higher B.P than tar
gulf Bitumen?
why bitumen is used
What is the difference between penetration and softening point of a bitumen?
The penetration point of Bitumens such as asphalt is the depth in tenths of millimeters a standard weighted needle will penetrate through a given sample of asphalt at a given time and temperature. The softening point of Bitumen such as asphalt is the temperature at which the Bitumen softens at standard conditions. Method of detrmination employs a ball and ring in which the ball falls through the ring after the softening has been reached.
