BITUMEN PENETRATION 40/50
Bitumen Penetration 40/50 is a standard penetration-grade paving bitumen, produced under ASTM D946M and AASHTO M20-70 specifications. It has a penetration range of 40–50 dmm and a softening point of 52–60°C, giving it a firmer, less temperature-sensitive body than the more common 60/70 grade. This makes it the preferred choice for hot climates and heavy-traffic roads, where a softer bitumen would deform under load and heat.
USAGE OF ASPHALT
Raha Oil’s Bitumen 40/50 is produced from vacuum-bottom feedstock through a controlled air-blowing process, then refined to remove excess hydrocarbons. Its thermoplastic behavior — softening under heat, hardening in the cold — combined with its relatively strong viscosity, makes it well suited to hot mix asphalt production for base and wearing courses. Because of its higher resistance to softening, this grade holds up particularly well on roads and airport runways in tropical and desert climates, where surface temperatures regularly exceed those in temperate regions.
PPLICATION OF BITUMEN 40/50
- Road base and wearing-course construction in hot climates
- Airport runway and taxiway asphalt
- Heavy-traffic highway pavements where deformation resistance matters
- Any application requiring a stiffer penetration grade than 60/70
BITUMEN PENETRATION 40/50 PRICE
Bitumen 40/50 pricing varies by origin, freight route, and packing type, since no two refineries produce an identical product even under the same ASTM specification. Raha Oil supplies Bitumen 40/50 FOB Jebel Ali, UAE, in bulk, jumbo bags, and new steel drums, with quality verified by an independent international inspector at loading and confirmed by batch QC test reports before shipment.

PENETRATION 40/50 ADVANTAGE
- Thermoplastic behavior: flexible in heat, rigid in cold
- Strong, long-lasting adhesion across substrate types
- Higher resistance to softening than lower-penetration grades — ideal for tropical climates
- Long service life on high-traffic pavements
THE 4 MAJOR TEST OF BITUMEN 40/50
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.
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.
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 AND SAFETY OF PENETRATION 40/50
Raha Oil guarantees the quality of Bitumen Penetration 40/50 by appointing an independent international inspector to verify quality and quantity during vessel loading, alongside in-house QC batch testing prior to shipment — ensuring full compliance with ASTM D946 and AASHTO M20-70.

FREQUENTLY ASKED QUESTIONS - FAQ
Bitumen 40/50 is a penetration-grade paving bitumen with a penetration range of 40–50 dmm, produced under ASTM D946M and AASHTO M20-70 standards. It is firmer than 60/70 grade and better suited to hot climates and heavy-traffic roads.
Bitumen 40/50 has a lower penetration value and higher softening point (52–60°C vs 46°C for 60/70), making it harder and more heat-resistant — ideal for tropical regions and high-load pavements, while 60/70 is more common in temperate climates.
