Bitumen is a hydrocarbon product of natural or pyrogenous origin. Typically, bituminous materials are made of graded aggregates and bitumen. There is a small quantity of air as well in the bituminous materials, which makes it a three-phase material. Bituminous materials are typically composed of 80 to 87% of bitumen by weight.

Aging of bitumen. Bitumen is a primary engineering material,due to its low cost as compared to other binding materials it is used in relatively thick films to provide protective film against corrosive influences and weather.Bitumen is a dense viscous material,dark black or brown in color,used as a binding and waterproofing material.

Bitumen is defined by the U.S. Geological Survey as an extra-heavy oil with an API gravity less than 10° and a viscosity greater than 10,000 centipoise. At the temperatures normally encountered in natural deposits, bitumen will not flow; in order to be moved through a pipe, it must be heated and, in some cases, diluted with a lighter oil.
