Bitumen emulsion production has various methods, each involving a different process for combining bitumen with water and an emulsifying agent. In the production of asphalt emulsions, the manufacturers use materials such as pure or polymer-modified bitumen, water, acid, emulsifier, calcium chloride, and, if needed, hydrocarbon solvents. The emulsifier creates an electric charge on the bitumen […]
The difference between natural bitumen and petroleum bitumen is in their origin, chemical composition, and physical properties. Natural bitumen, or mineral bitumen, is extracted from mines and is a product of long-term geological processes on crude oil. In contrast, petroleum bitumen is a byproduct of crude oil refinement and is obtained through the distillation of […]
The difference between asphalt and bitumen is evident in their nature, applications, and durability. Bitumen is a sticky, waterproof material used for insulation. On the other hand, asphalt is a mixture of bitumen and durable aggregates, which makes it ideal for paving high-traffic roads. Asphalt is more durable than bitumen and requires fewer maintenance and […]
What is hard bitumen? Hard bitumen is a petroleum product known in the market as bitumen 90/15 and is available in both barrel and carton forms. Bitumen 90/15 is produced through the distillation of oil and by heating soft bitumen. Also, this bitumen has water-resistant properties, heat resistance, and long-term stability. It is useful in […]
What is white bitumen? While we’re used to black bitumen, there is also a bitumen known as a waterproof membrane. This bitumen has strong waterproofing properties and shares many characteristics with black bitumen, such as viscosity and adhesiveness. Because of this, it has various applications, including construction, waterproofing membranes, plastic and paint production, pipe insulation, […]
What is dry bitumen? Dry bitumen is a modified bitumen that manufacturers produce through thermal and air-blowing processes. It comes in various grades, including 10/20, 115/15, and 160/220. These processes reduce volatile components and increase bitumen’s hardness and brittleness, producing a glossy and solid bitumen. Also, dry asphalt is available in two forms: pure dry […]
MC bitumen is a mixture of bitumen and petroleum solvent. Therefore, it has various characteristics and specifications, including good viscosity, controlled curing time, and heat resistance. Due to these features, medium-curing bitumen has many uses and applications, such as constructing protective asphalt, single-coat surface dressing, and continuous grading. However, medium-curing bitumen is not just one […]
Colored bitumen is essentially the same as black bitumen. However, its manufacturers improve the black bitumen’s properties and performance by applying certain processes and adding chemicals to it. Therefore, colored bitumen has high flexibility, resistance, and adhesion. Additionally, it has numerous uses, the most important of which are road surfacing and construction. But how exactly […]
The best bitumen solvent includes pre-made and organic solvents, petroleum derivatives, and others. These substances can remove bitumen from various surfaces due to their high dissolving ability. The method of bitumen removal varies based on the type of surface. For example, different solvents are usable for metal surfaces, stone and ceramic surfaces, fabric, and skin. […]
What is ready bitumen? Ready asphalt or bitumen is a versatile, durable waterproofing material and a byproduct of crude oil. It is water resistant, high adhesive, and cost-effective, which makes it an excellent choice for sealing joints, patching, waterproofing, and insulating surfaces such as rooftops, air conditioner floors, and more. Furthermore, ready asphalt has low […]
The prime coat and tack coat difference is an important topic in road construction and asphalt production, as it directly impacts the quality and performance of road layers. The distinction between prime coat and tack coat relates to the type of materials used, their applications and purposes, the execution process, and their consumption rates. Prime […]
Iran bitumen refineries play a crucial role in road construction and buildings. Bitumen manufacturers such as Petro Arton, Ansar Howeyzeh, Fanavar Gostar Peyman, and Kimia Jey use advanced technologies to produce various industrial bitumen, asphalt, and waterproofing materials. Additionally, companies like Brent Pars, Ghir Dezhpa, and Ghiran Pakhsh contribute significantly to Iran’s infrastructure development by […]
