Bitumen #40 Description:
Bitumen 40 is a very soft grade of oxidized asphalt derived from bitumen #60 through a specific extraction process. This asphalt grade is characterized by its flexibility, even though it has a relatively high softening point. Typically, Bitumen 40 is packaged in steel drums. It is commonly used in road construction to enhance asphalt stability, particularly in hot weather conditions where movement can be a concern.
Product Name: Bitumen 40
Description: Bitumen 40 is an exceptionally soft grade of oxidized asphalt produced through the extraction of bitumen #60. Despite its high softening point, it retains a remarkable degree of flexibility, making it suitable for various applications. This grade of asphalt is typically packaged in steel drums.
Applications: Bitumen #40 finds utility in a range of applications, including:
- Underground Moisture Waterproofing: Used to protect underground structures from moisture infiltration.
- Nuclear Power Engineering: Employed in nuclear power engineering projects for pipeline engineering, bottom anticorrosion, and asphalt production.
- Waterproofing Membrane and Moisture-Proof Paper Production: Utilized in the manufacturing of waterproofing membranes and moisture-resistant paper products.
- Anti-corrosion Paint and Waterproof Production: An ingredient in the production of anti-corrosion paints and waterproofing materials.
- Road and Bridge Caulking: Used for sealing and caulking purposes in road and bridge construction projects.
Packaging: Bitumen 40 is typically packaged in steel drums due to its soft nature and the need for secure containment.
