What is Bitumen (#Asphalt)?

Asphalt is a dark brown or black cementitious material which is a natural constituent of must crude oils found throughout the word.

Asphalt is a dark brown to black ,highly viscous ,hydrocarbon produced from #petroleum #distillation residue.(US FHWA)

Is a dark brown to black cementitious material in which the predominating constituents are bitumen’s which occur in #nature or are obtained in petroleum processing. (ASTM D8)

A virtually in volatile ,#adhesive and #waterproofing material obtained by #refinery processes from crude petroleum ,or present in natural asphalt deposits in some parts of the world .it is black or brown in color and completely or nearly completely #soluble in toluene .it is very viscous or near solid at ambient temperatures and softens gradually when heated.

A class of amorphous, black or dark colored,(solid, semi-solid or viscous)

Cementitious substances, natural or #manufactured, composed principally or high molecular weight hydrocarbons, soluble in carbon disulfide, and found in asphalts, #tars, #pitches and #asphaltites.

A generic term used to denote any material composed principally of bitumen.

Definition:

.

A process by which components in a chemical mixture are separated according

To their different boiling points . Vapors from boiling solutions are passed along a column. The temperature of the column gradually decreases along its length. Components with a higher boiling point condense on the column and return to the solution.

Components with the lower boiling point pass through the column and are collected.
