bitumen 40

Bitumen 40

Bitumen 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.

Uses of bitumen #40

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