This table presents the test results and properties of a specific sample of Modified Bitumen PG 82 – 22. These tests were conducted following ASTM (American Society for Testing and Materials) and AASHTO (American Association of State Highway and Transportation Officials) M320 standards.

Here’s a breakdown of the key elements in the table:
1. Penetration @25C, ASTM D5: 33 mm/10 – This is a measure of the hardness or softness of the bitumen at 25 degrees Celsius. The penetration depth was found to be 33, measured in tenths of a millimeter (mm/10).
2. Ductility @25C, ASTM D113: >120 > 100 cm – This is the extent to which the bitumen sample can be stretched at 25 degrees Celsius before it breaks. The ductility of this sample was found to be greater than 120 cm, surpassing the reference minimum of 100 cm.
3. Softening Point, ASTM D36: 70 > 49 – The softening point is the temperature at which the bitumen becomes soft enough to flow. The sample’s softening point was found to be 70 degrees Celsius, which is higher than the reference minimum of 49 degrees.
4. Flash Point, ASTM D92: > 300 > 250 °C – The flash point is the temperature at which the bitumen vapors can ignite. The flash point of this sample is above 300 degrees Celsius, surpassing the reference minimum of 250 degrees.
5. Specific Gravity @25C, ASTM D70: 1.03 1.011 – 1.05 – This is a measure of the density of the bitumen in relation to the density of water at 25 degrees Celsius. The specific gravity of this sample was found to be 1.03, which falls within the reference range.
6. Loss on Heating W%, ASTM D6: 0.12 < 0.5% – This is the percentage of weight the bitumen loses when it is heated. The sample’s loss on heating was 0.12%, which is less than the reference maximum of 0.5%.
7. Elastic Recovery @25C, ASTM D6084: 62% – This is a measure of the bitumen’s ability to recover its original shape after being deformed. The bitumen sample showed an elastic recovery of 62% at 25 degrees Celsius.

The second part of the table presents the properties of the original binder and its behavior after short-term and long-term aging. These properties include G*/SIN Delta, a measure of the binder’s rutting resistance, with the “True Grade” representing the effective temperature range of the binder.

In conclusion, the Modified Bitumen PG 82 – 22 sample has been thoroughly tested and demonstrated satisfactory performance according to the ASTM D6373 and AASHTO M320 standards.
