Bitumen number 40 is made by the extract of bitumen #60 and it is the very soft grade of oxidized asphalt that should be packed in the steel drum.
It is flexible bitumen while the softening point is high.
This type of asphalt is useful to use in road construction to keep the asphalt stable against hot season and movement.

Applications Bitumen No. 40#

1. Used For underground moisture, waterproofing works
2. Used For nuclear power engineering, pipeline engineering, bottom anticorrosion, asphalt production of the production
3. Used For waterproofing membrane, moisture-proof paper production, etc.
4. Used For Anti-corrosion paint and waterproof production
5. Used for road and bridge caulking use

Bitumen No. 40 Packing
bitumen #40 in various packing including kraft bag, meltable plastic bag, drum and bulk,it is made by hot air in a controlled process until the desired specification is reached.
Bitumen #40 means softening point is 75°c and penetration is 10 desimillimiter is produced in compliance and conformity to Astm standard and meets the mentioned specification.
