In the laboratory, to determine an index of bitumen adhesion, they measure the amount of bitumen’s plasticity; the more the bitumen is adherent, the more sticky it is. Bitumen ductility properties are the incremental length of a bitumen specimen in centimeters drawn at a standard rate (at a specified speed and at a specified temperature) to reach rupture or discontinuity. The length of the specimen just prior to tearing in centimeters is called ductility or stiffness.

Bitumen hardness is one of the factors affecting the swelling properties. That is, the harder and more brittle the bitumen is, the less its pungency and vice versa. Therefore, it should be kept in mind that if bitumen is used in a cold environment, it has a good sealing effect to prevent cracking in the asphalt. We know that as a result of vehicles passing through the road, there are tensions in the asphalt that cause slight movements in the asphalt bitumen, and if bitumen cannot tolerate these movements, especially in the cold season, one should expect To have cracks in the asphalt.

Temperature is another factor that can affect the bitumen properties of bitumen so that the bitumen property of any body is carried out at a particular temperature and that the bitumen is resistant to changes in temperature that cause it to expand and shrink, It should have a good stinging effect.
