asphalt

n. black tar-like substance used for paving and roofing

v. cover with asphalt, pave with asphalt

The term asphalt is often used as an abbreviation for asphalt concrete. For the film, see Asphalt (film); for the novel, see Carl Hancock Rux. Asphalt is a sticky, black and highly viscous liquid or semi-solid that is present in most crude petroleums and in some natural deposits. It is most commonly modeled as a colloid, with asphaltenes as the dispersed phase and maltenes as the continuous phase (though there is some disagreement amongst chemists regarding its structure). In U.S. terminology, asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside North America, the product is called bitumen.
