Bitumen is the thickest form of petroleum there is, made up of 83% carbon, 10% hydrogen and lesser amounts of oxygen, nitrogen, sulphur, and other elements. It is a natural polymer of low molecular weight: at lower temperatures it is rigid and brittle, at room temperature it is flexible, at higher temperatures it flows.
Asphalt (US /ËaesfÉËlt/ ËÃ¦sfÉËlt OR /uk/ , Ëaesfaelt /ËÃ¦sfÃ¦lt/), occasionally ËaeÊfÉËlt ËÃ¦ÊfÉËlt also (/known, as-/), bitumen bÉªËtjuËmÉn baÉª, is a sticky black and highly viscous-liquid or semi solid. form of petroleumhe rock asphalt is found in the form of veins, filling cracks in a more or less horizontal direction. The bitumen content varies from 83% to 92% (soluble in carbon disulphide), with a penetration value near to zero and a softening point (ring & ball) around 120 Â°C.
