Bitumen is a petroleum-based hydrocarbon that is obtained by distilling crude oil. Bitumen is also known as tar or pitch at times. Bitumen is also found naturally at the bottom of ancient lakes and has a wide range of industrial applications. Bitumen is commonly used in the construction due to its outstanding adhesive and waterproofing properties. Under severe weights, it can permanently distort. Furthermore, because of its low melting point, bitumen can be recycled. Bitumen was formerly supplied only black, but because to the addition of pigments, it is now accessible in a range of hues.

Bitumen is a material created during the distillation of crude oil. Bitumen is widely utilised in the construction sector, particularly for roads and highways, due to its waterproofing and adhesive characteristics. Distillation eliminates lighter crude oil components like gasoline and diesel, leaving only the heavier bitumen remaining. Deposits can also form naturally at the bottom of ancient lakes, where prehistoric animals decompose and are subjected to heat and pressure.

Bitumen is a byproduct of crude oil production. It is made up of complex hydrocarbons and contains calcium, iron, sulphur, and oxygen. The source and type of crude oil from which it is generated determine the material's quality and simplicity of manufacture. It was initially employed for its natural adhesive and waterproofing properties, which helped to bind building materials together and line ship bottoms. Under severe weights, Bitumen might permanently distort. Cracking can occur if the material is subjected to continuous stress. It oxidises, making the asphalt brittle. The manner it changes shape is determined by several factors, including the composition of the asphalt mixture and the ambient temperature.

Bitumen is a petroleum-derived binding agent. Bitumen is well-known for its high adhesive strength and resistance to water and oil spills. Because asphalt is often utilised as a surface for roadways, parking lots, and driveways, bitumen is the best binder for asphalt.

Bitumen can be made to varying standards depending on how it will be used, but it is always produced by distilling crude oil. This procedure eliminates the lighter liquid, leaving a thick sticky solution that, in the case of asphalt, will hold heavy aggregate like as stones and gravel together with sand.

Bitumen, commonly known as asphalt is a sticky, black, very viscous liquid or semi-solid petroleum product. It is classified as a pitch and can be found in natural deposits or as a refined product. Before the twentieth century, the term asphaltum was also used.  The word is derived from the Ancient Greek o ásphaltos. The largest natural asphalt deposit in the world, estimated to hold 10 million tonnes, is the Pitch Lake in southwest Trinidad (Antilles island on Venezuela's northeastern coast), within the Siparia Regional Corporation.
