What is bitumen 90/40
It is soft grade of oxidized bitumen with softening port 90C + 5 and penetration 40 +5 desimillimiter. Bitumen 90/40 is semi solid with some flexibility compare hard grades and mostly using in African market.
How bitumen 90/40 produce?
Bitumen is a type hydrocarbon and after destination and remove of hydrogen more carbon will remove and become harder. By injecting hot air to bitumen the oxygen of air will combine with hydrogen of bitumen and make H2O and vapour and the remain bitumen is more carbon content and called oxidized bitumen.
