Bitumen 85/40: An Introduction to This High-Performance Grade
Bitumen 85/40 is a partially oxidized petroleum product renowned for its outstanding heat resistance
and waterproofing abilities. From the very beginning of production, hot air is applied to standard
bitumen to increase its softening point and improve its overall durability. As a result, this grade
excels in challenging conditions and suits many construction and industrial uses.
Our team at Gold Bitumen ensures every batch of this oxidized bitumen meets stringent industry standards.
We also invite independent inspectors to confirm quality and quantity before shipment, allowing you
to trust in the consistency of each order.
Key Features of Bitumen 85/40
Oxidized bitumen, such as bitumen 85/40, shows impressive resistance to temperature swings and moisture.
This unique profile emerges from a specialized manufacturing process, where forced hot air alters the
molecular structure. Consequently, it stays stiff at higher temperatures yet maintains enough flexibility
in moderate climates.
Applications of Garid 85/40
This particular bitumen grade is valuable in various industries due to its stability and long-lasting
performance. Here are some of its common applications:
- Road construction: Delivers improved durability against heavy traffic and heat.
- Roofing and waterproofing: Provides a reliable seal against rain and humidity.
- Industrial coatings: Defends metal surfaces, pipelines, and tanks against corrosion.
- Automotive undercoating: Lowers noise and protects vehicle undersides from moisture.
Handling & Packaging for Bitumen 85/40
Proper handling ensures that Garid 85/40 retains its enhanced properties. Typically, it should be heated
to around twice its softening point for optimal application. In addition, suppliers may provide this grade
in drums, meltable plastic bags, or Kraft bags, based on project scope and storage conditions.
Quality Assurance for This Grade
Most manufacturers test their oxidized bitumen products, including Garid 85/40, to ensure compliance
with recognized standards. Through careful quality control, they check penetration, softening point, and
other vital parameters. This meticulous process ensures that end users receive a reliable product for
demanding environments.
FAQ
Here are the most common questions and answers about Bitumen 85/40:
