Producer of Paving Grade Bitumen 30/40

General description of Bitumen 30/40

Penetration Grade Bitumen 30/40 are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. The Bitumen mode is dependent on temperature.
The temperature-vs-stiffness relationship of bitumen is dependent on the type of crude oil and its refining method. Blown Asphalt is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. It is a kind of bitumen and standard penetration grade. This type is petroleum-grade bitumen, manufactured from fractional- vacuum destination of crude oil.

Bitumen Grade 30-40 is Semi-Hard penetration grade bitumen used as Paving Grade Bitumen suitable for road construction and repair also for the production of Asphalt pavements with below Penetration Bitumen 30/40 Specifications. Penetration determines the hardness of bitumen by measuring the depth to which a standard loaded needle will vertically penetrate in 5 seconds, in a sample of bitumen maintained at a temperature of 25 degrees Celsius.

Application of Paving Grade 30/40

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 grade. 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 30/40

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 30/40 bitumen means the penetration value is in the range 30 to 40 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 Penetration Grade 30/40

Quality of bitumen penetration grade with the arrangement of the international inspector to check the quality and quantity of the bitumen penetration grade 30/40 during the loading to the vessel and controlling the production by QC by batch test report before shipping.

Packing of Bitumen grade 30/40

Bitumen’s packaging is a real concern especially if it’s meant to be exported, the better and safer packaging, guarantees the better delivery of the cargo. There are several different ways to package the bitumen which can vary depending on the tonnage, type, and grade of the bitumen- as mentioned before, different grades of bitumen have different levels of stiffness and viscosity- so the grade also plays an important role in choosing a suitable packaging. Bitumen grade 30/40 is commonly packed in new steel drums, 150, 180 & 220 Kg barrels and Jumbo Bags or 300 Kg Bitubag.
