उत्पाद वर्णन

they are typically defined by standards organizations or regulatory bodies. Here are some common specifications for bitumen:

1. Penetration Grade: Bitumen is often classified by penetration grade, which is a measure of its hardness. Common penetration grades include 40/50, 60/70, 80/100, where the numbers indicate the penetration depth of a standard needle in units of 0.1 mm at 25 degrees Celsius.

2. Performance Grade (PG): In the United States, bitumen is often specified using the Performance Grade system, which considers the temperature susceptibility and performance characteristics of bitumen. PG grades are defined by the climatic conditions in which the bitumen is expected to perform.

3. Viscosity Grade: Bitumen can also be classified based on its viscosity at a specific temperature. Common viscosity grades include AC-10, AC-20, AC-30, AC-40, where AC stands for Asphalt Cement.

4. Cementation Factor: This factor is used in the classification of bitumen in some regions. It is a measure of the adhesive strength of bitumen.

5. Ductility: Ductility is a measure of the bitumen's ability to deform under tensile stress. Specifications often include minimum ductility values.

6. Softening Point: The softening point is the temperature at which bitumen softens under a specified load. It is a crucial parameter in determining the suitability of bitumen for certain applications.

7. Flash Point: This is the temperature at which bitumen can ignite when exposed to an open flame or heat source.

8. Solubility: Bitumen specifications may include requirements for solubility in certain solvents, indicating the purity of the bitumen.
