Bitumen is a beneficial material that is used in various industries. It is a thermoplastic material and its stiffness is dependent on temperature. The temperature-vs-stiffness relationship of bitumen is dependent on the source of crude oil and the method of refining. More than 85% of the world’s bitumen production is used for road construction, 10% is used in other constructions and 5% is used in a variety of other industries, including insulation Viscosity grade bitumen is classified based on its viscosity after production of the bitumen in the refinery.
