One important byproduct of ordinary bitumen that has gone through a regulated oxidation process is blown bitumen. The output of this transition has unique qualities that make it perfect for a range of uses. Because of its higher softening point and better tolerance to temperature changes, blown bitumen is a great material to use for waterproofing, roofing, and road building applications. Depending on the level of oxidation, its consistency can vary from being extremely viscous and brittle to being more elastic, which makes it flexible and adaptable for a variety of uses.
