Tests performed on First rate bitumen determine some of the types of bitumen, including penetration grade, viscosity grade and performance grade. Bitumen tests include viscosity, penetration, spot test, and که, which examine bitumen from different dimensions and determine for what area and for what purpose the test sample is used. Therefore, Iran is one of the First rate bitumen Exporting Countries.
Is bitumen solid or liquid?
Bitumen is a black, pasty material used in moisture insulation and asphalt construction. There are different types of bitumen, each of which has a specific application. Bitumen is a derivative of oil and is often produced in oil refineries.
Bitumen is a black to dark brown hydrocarbon that dissolves completely in carbon sulfide and carbon tetrachloride. Bitumen is solid at ambient temperature. But as the temperature rises, it becomes a paste and then liquefies.
The important use of bitumen is due to the existence of two important properties of this material;
- Waterproof
- adhesion
Bitumen is usually obtained by distilling crude oil. Such bitumen is called petroleum bitumen or distilled bitumen. Petroleum bitumen is the product of two stages of crude oil distillation in the distillation tower. In the first stage of distillation, light materials such as gasoline and propane are separated from crude oil. This process takes place at a pressure close to one atmosphere (units). In the second stage, heavy compounds such as diesel and kerosene are extracted. This process takes place at a pressure close to vacuum. Eventually a mixture of very fine solid particles called asphaltene remains, which is immersed in a grease-like fluid called malton.
Types and sources of bitumen and applications
Bitumen is a hydrocarbon material that has a definition, properties, resources and special properties. Bituminous materials are also more diverse than oil, because bitumen has other sources besides oil. Bitumens are divided into the following three categories depending on the origin:
Bitumen is a natural hydrocarbon resin that has been rediscovered in modern history on the Bonita River in northeastern Utah. This natural asphalt has hardened like a crude oil asphalt. Usually, the names asphalt, euthanate and asphaltum are also used for this material. “Natural bitumen, like natural asphalt, is soluble in aliphatic and aromatic solvents.” Due to the high compatibility of this product, it is usually used to harden dilute petroleum derivatives.
Bitumen in lumpy state is a glossy, black substance, very similar to obsidian, and very brittle, and in micronized powder form it has a dark brown color. Bitumen is found in vertical layers below the ground. Due to the narrow mining front, bitumen is now mined using excavators, loaders, hammers, and other new mechanical tools.
Natural bitumen, also known as bentonite, asphaltite, natural asphalt, decorative asphalt, asphalt, and mineral bitumen, is a natural hydrocarbon resin and is the best waterproofing in nature. Bitumen is a glossy, black and very brittle material in the lumpy state and has a dark brown color in the micronized powder state. Bitumen is found in vertical layers below the ground.
Bitumen is an additive raw material that modifies waterproofing, which by increasing the properties of waterproofing, volume, plays an alternative role of raw materials and other additives. Consumer products are used in the civil engineering sector due to the promotion of the softening point and creating more resistance to heat in the role of thermal modifier.
