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.
Naturally occurring asphalt/bitumen is sometimes specified by the term crude bitumen. Its viscosity is similar to that of cold molasses while the material obtained from the fractional distillation of crude oil boiling at 525 Â°C (977 Â°F) is sometimes referred to as refined bitumen.he asphalt/bitumen in the removed material can be reactivated and put back to use in new pavement mixes. With some 95% of paved roads being constructed of or surfaced with asphalt, a substantial amount of asphalt pavement material is reclaimed each year.
