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....
What is another word for bitumen?
Bitumen is a petroleum tar, known as asphalt, pitch, or blacktop.
What is bitumen pitch?
bitumen pitch means road surface
Is a road rough?
yes it is because the surface of the bitumen is hard.

Why roads are in black colour?
Black is the colour of the tar used to surface the road. Tar and bitumen are two important binders for road making. Tar is a by- product of coke and bitumen come from refining crude petroleum.

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.
