Penetration Grade Bitumen 50/70 is a paving-grade bitumen selected for road construction and asphalt applications where improved stiffness and resistance to deformation are required compared to standard penetration grades.
Kiapetro manufactures, supplies, and exports bitumen 50/70 for international infrastructure projects, providing controlled quality, certified inspection, and export-ready logistics. This grade is commonly used in roads and asphalt layers operating under moderate to warm climate conditions and sustained traffic loads.
What is the bitumen 50/70 price?
Since Iran has a big part of the world’s Penetration grade bitumen 50/70, knowing the market price in Iran can help people working in this industry. We have some factors, like quality of the product and the brand are important.
How can bitumen 50/70 be made?
The creation of Penetration grade bitumen 50/70 involved breaking down crude oil using a method called fractional distillation. This method separates the parts of crude oil by their boiling points, creating a material with specific abilities to penetrate.
As time went on, rules and checks were put in place to make sure everything was the same and worked well. Bitumen 50 70 is a common type of bitumen used in industries like building and road projects. The numbers “50/70” show how hard and thick the bitumen is.
With a hardness level between 50 and 70, it’s quite tough, making it great for warmer areas where a strong road surface is needed. This kind of bitumen is known for being strong, not letting water through, and sticking well to other materials, especially when combined with rocks to make asphalt.
Penetration grade bitumen 50/70 specification
Penetration grade bitumen 50/70 is a specific type of bitumen, often referred to as asphalt cement, defined by its penetration value that lies between 50 and 70 tenths of a millimeter (5.0 to 7.0 millimeters). This value reflects the stiffness of the bitumen and its suitability for different uses in road construction and industrial applications.
This type of bitumen 50/70 is primarily utilized in producing hot mix asphalt for both base layers and surface courses. Penetration grade Bitumen 50/70 is a thermoplastic substance that gradually softens when heated and solidifies as it cools. The distinctive relationship between temperature and stickiness is crucial for assessing its performance characteristics.
Bitumen 50/70 and its application
This Penetration grade bitumen is utilized through different methods, including hot mix asphalt paving, spraying techniques, and bituminous macadam. The selection of the application method is based on the particular requirements of the project, including the surface type, traffic demands, and environmental factors. It is important to mention that this product is primarily applied in road construction within tropical areas.
Penetration grade bitumen 50/70 provides outstanding durability and long-lasting performance, which makes it a popular option for busy roads and infrastructure initiatives. Its ability to resist cracking, deformation, and environmental damage guarantees an extended service life and lower upkeep expenses.
Bitumen 50/70 price and its cost-efficiency
The cost-effectiveness of penetration grade bitumen 50/70 stems from its adaptability and low maintenance requirements. While the upfront cost may be greater than that of alternative materials, its enduring efficiency and lower repair demands have led to overall savings.
As mentioned earlier Crude oil is the primary ingredient in penetration grade bitumen 50/70, so fluctuations in its price will consequently impact the cost of 50/70 bitumen. The cost of the product varies based on several factors, including the type of material required and its quality.
