what is bitumen 75/25?
It is hard and breakable bitumen with softening port 75C + 5 and penetration 25 +5 desimillimiter. To be able to test softening point of bitumen 75/25, need to use other high temperature fluid instead of water like liquid paraffin or silicone fluid to do not vapour during the test.(water will vapour on 100C).The test should be arranged in ISO mode means in controlled temperature at 25C and P:1 atmosphere.
How bitumen 75/25 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.
