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 […]
What is bitumen spray? Bitumen or asphalt spray has many applications in the construction and insulation industries. For Example, asphalt spray can prevent water and moisture absorption by surfaces. This spray, also known as a waterproof spray, is made from liquid bitumen and is evenly applied to various surfaces using a sprayer. Asphalt spray has […]
Vacuum Bottom bitumen is derived from the residue of crude oil distillation in distillation towers. Visually, VB bitumen is dark brown or black and is very flammable. Interestingly, in the past, this bitumen was discarded as waste. However, with technological advancements, it now has uses in various industries such as construction and insulation. That being […]
Different types of construction bitumen are used in the construction industry for insulation and to increase the durability of structures, depending on their specific properties. The uses of bitumen for construction include insulation, asphalt paving, and repairs. Common types of bitumen include bitumen 60/70 (soft bitumen), 25-85 bitumen (bitumeninous mixture), 15-90 bitumen (hard bitumen), blown […]
