Manufacture of Bitumen grade 40/50

General definition of Bitumen 40/50

Bitumen penetration grade 40/50 is semi-hard penetration grade bitumen used as a paving grade bitumen which is suitable for road construction and repair. This unique temperature-viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability, and application temperatures of bitumen. bitumen is a standard Penetration Grade of Bitumen ASTM D946M, typically used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties particularly in road and airport constructions and other similar applications. Penetration grade Blown Asphalt 40/50 has penetration between 40~50 desi-millimeter and the softening point between 52 ~ 60C. The penetration grade Bitumen 40/50 has a thermoplastic property which is like synthetic resin material which gets softer with heating and hardens when cooled. This grade of Asphalt 40/50 has a very strong viscosity compared to other grades.

Bloawn Asphalt is a standard Penetration Grade of Bitumen ASTM D946M, typically used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties particularly in road and airport constructions and other similar applications. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grades of Bitumen is produced from Vacuum Residue, which is blown by hot in the Biturox Blowing Unit; The fully automated process runs continuously resulting in a constant and homogeneous finished product quality. Wataniya’s Penetration Grade Bitumen can be supplied in any grade and are designated by two numbers to indicate the mid-points of their penetration ranges.

Application of Bitumen grade 40/50

This grade of bitumen is also mainly used in the manufacture of hot mix asphalt. also, Bitumen is suitable for road construction and repair for asphalt pavements with superior properties. Bitumen is used for hot mixed asphalt because of the properties of very strong viscosity compared to other grades. Also used in specialized applications like airport runways and also in very heavy traffic volume roads in coastal cities in the country.

the 4 Major of Bitumen 40/50

1. Penetration Test
2. Softening Point Test
3. Ductility Test
4. viscosity test

1.Penetration test:

It measures the hardness or softness of bitumen by measuring the depth in tenths of a millimeter to which a standard loaded needle will penetrate vertically in 5 seconds. BIS had standardised the equipment and test procedure.

A grade of 40/50 bitumen means the penetration value is in the range 40 to 50 at standard test conditions. In hot climates, a lower penetration grade is preferred. Figure 0.1 shows a schematic Penetration Test setup.

2.Softening Point Test:

Softening point denotes the temperature at which the bitumen attains a particular degree of softening under the specifications of test. The test is conducted by using Ring and Ball apparatus. Also Temperature is noted when the softened bitumen touches the metal plate which is at a specified distance below. Generally, higher softening point indicates lower temperature susceptibility and is preferred in hot climates. Figure 0.1 shows Softening Point test setup.

3.Ductility Test:

Ductility is the property of bitumen that permits it to undergo great deformation or elongation. Ductility is defined as the distance in cm, to which a standard sample or briquette of the material will be elongated without breaking.

4.viscosity test:

Viscosity denotes the fluid property of the bituminous material and it is a measure of resistance to flow. At the application temperature, this characteristic greatly influences the strength of resulting paving mixes. Low or high viscosity during compaction or mixing has been observed to result in lower stability values.

Guaranty of bitumen 40/50

Quality of bitumen penetration grade with the arrangement of the international inspector to check the quality and quantity of the bitumen penetration grade during the loading to the vessel and control the production by QC by batch test report before shipping.
