Asphalt Production and Oil Refining – Pavement Interactive

This process of boiling and reboiling a batch of crude oil is the simplest form of refining, or distillation; it is commonly called batch distillation. However, this process of boiling off fractions of crude oil is not the most efficient way to produce petroleum products. In the 1920s, fractional distillation was developed.

Asphalt - Wikipedia

Asphalt, also known as bitumen (UK: / ˈ b ɪ tj ʊ m ɪ n /, US: / b ɪ ˈ tj uː m ə n, b aɪ-/), is a sticky, black, highly viscous liquid or semi-solid form of petroleum.It may be found in natural deposits or may be a refined product, and is classed as a pitch.Before the 20th century, the term asphaltum was also used. The word is derived from the Ancient Greek ἄσφαλτος ásphaltos.
