|Asphalt |Asphalt is a sticky, black and highly viscous liquid or semi-solid that is present in most crude petroleums and in some |
| |natural deposits. Asphalt is composed almost entirely of bitumen. There is some disagreement amongst chemists regarding the |
| |structure of asphalt, however it is most commonly modelled as a colloid, with asphaltenes as the dispersed phase and maltenes|
| |as the continuous phase. |
| | |
| |Asphalt is sometimes confused with tar, which is an artificial material produced by the destructive distillation of organic |
| |matter. Tar is also predominantly composed of bitumen, however the bitumen content of tar is typically lower than that of |
| |asphalt. Tar and asphalt have very different engineering properties. |
