The table represents the specifications and properties of a sample of Cut-back MC-30 bitumen, tested using various ASTM standards. The sample conforms to the standard ASTM D2027M-13, which specifies requirements for cutback asphalt (liquid petroleum bitumen) that is suitable for use as a paving material.

Here’s a breakdown of each row:
1. Kinematic Viscosity @60°C – ASTMD2170: 50 Cst: This measure of the resistance to flow (or thickness) of the bitumen at 60°C obtained a value of 50 centistokes (Cst), which falls within the accepted reference range of 30 to 60 Cst.
2. Flash Point – ASTMD3143: 65 °C: The flash point is the temperature at which bitumen vapors ignite in the presence of an ignition source. This bitumen’s flash point was found to be 65°C, which is above the minimum reference value of 38°C.
3. Density @ 15.6 °C – ASTMD287: 0.945 g/cm3: This measures the mass per unit volume of the bitumen at 15.6°C, and was found to be 0.945 g/cm3.
4. Water Content – ASTMD95: 0.00 %: This test measures the percentage of water in the bitumen. The test found no water (0.00%) in the sample, which is below the maximum allowed reference of 0.2%.
5. Distillation Test – ASTMD402: This test provides the boiling range of bitumen by noting the volume of distillate obtained at certain temperatures. The distillation results at various temperatures (190°C, 225°C, 260°C, and 316°C) are all within the specified reference ranges.
6. Residue From Distillation To 360 °C: 70 %: This is the percentage of remaining material (residue) after distilling the bitumen to 360°C. The residue was found to be 70%, which is above the minimum reference of 55%.
7. Dynamic Viscosity @ 60 °C ASTMD4402: > 100 Poise (pas.s): This measure of resistance to flow under applied force found that the viscosity at 60°C was over 100 poise, which is above the minimum reference of 30 poise.
8. Ductility @ 25 °C ASTMD113: > 150 cm: This measures how much the bitumen can be stretched before it breaks. At 25°C, the bitumen could stretch more than 150 cm, exceeding the minimum reference of 100 cm.
9. Penetration ASTMD5: 180 mm/10: This measure of the hardness or softness of the bitumen found that the penetration was 180, which falls within the reference range of 120 – 300.
10. Solubility In TCE ASTMD2042: 99.60 %: This test measures the solubility of bitumen in trichloroethylene (TCE). The solubility of this bitumen was found to be 99.60%, exceeding the minimum reference of 99%.

In conclusion, the sample of Cut-back MC-30 bitumen not only meets all of the reference standards for its various properties, but it also conforms to ASTM D2027M-13, a standard specification for cutback asphalt.
