1. Specific Gravity
This parameter refers to the ratio of the weight of bitumen to the weight of an equal volume of water and represents the density of bitumen.
2. Viscosity
Viscosity indicates bitumen's resistance to flow. This parameter is measured at different temperatures and has a great impact on bitumen efficiency in different conditions.
3. Softening Point
The point at which bitumen softens under heat. This parameter is very important in determining the working temperature of bitumen.
4. Fraass Breaking Point
The point at which bitumen turns from flexibility to failure. This parameter indicates the bitumen's resistance to low temperatures.
5. Tensile and Flexural Strength
These parameters refer to the strength of bitumen in bearing different stresses that occur in different road and asphalt conditions.
6. Volatile Matter Content
Measuring the amount of volatile substances in bitumen that helps the efficiency and stability of bitumen.
7. Chemical Composition
Including the investigation of the hydrocarbon composition of bitumen and various components in it such as paraffins and aromatics.
8. Stability
Determining the ability of bitumen to maintain its physical and chemical properties over time and under different conditions.
conclusion
Bitumen analysis is very important in the construction and asphalting industry. By understanding these parameters, you can choose the right bitumen for different projects.
