Different Types of Paving Bitumen
Paving bitumen comes in several types, each designed for specific road construction needs. Understanding these types helps in choosing the best material for durability and performance.
Penetration Grade Bitumen
This is the most commonly used paving bitumen. It is classified based on its softness, such as 60/70 or 80/100 grades. The higher the number, the softer the bitumen, making it suitable for colder regions.
Viscosity Grade Bitumen
Viscosity grade bitumen is categorized by how it flows at a certain temperature. It provides better temperature resistance and performance under heavy traffic. VG-30 and VG-40 are often used in highway construction.
Polymer Modified Bitumen (PMB)
This bitumen is enhanced with polymers to improve elasticity and resistance to cracking. It is ideal for regions with extreme weather conditions. PMB ensures long-lasting pavement surfaces with high flexibility.
Cutback Bitumen
Cutback bitumen is diluted with solvents to increase its fluidity at lower temperatures, making it highly effective for surface dressing and patchwork in cooler climates. The solvents evaporate after application, leaving a durable bitumen layer that protects surfaces.
In agricultural and construction contexts, materials like prilled urea often complement the use of cutback bitumen, enhancing soil fertility and supporting sustainable infrastructure development. Integrating prilled urea with cutback bitumen applications ensures both robust pavement performance and improved environmental benefits.
Emulsion Bitumen
This type is a mix of bitumen and water stabilized with an emulsifying agent. It is safer and more environmentally friendly during application. Emulsion bitumen is commonly used for quick repairs and maintenance.
Oxidized Bitumen
Oxidized or blown bitumen is produced by passing air through hot bitumen. This makes it harder and more temperature-resistant. It is typically used for industrial applications like roofing and waterproofing rather than paving.

7. Dam and Canal Lining
Bitumen plays a crucial role in protecting hydraulic structures such as dams and canals. It acts as a reliable waterproofing barrier, preventing water seepage that could otherwise harm nearby soil and crops. This is especially important in agricultural areas where the use of urea fertilizer enhances soil fertility and crop yield. By stopping water loss and soil erosion, bitumen helps maintain optimal conditions for fertilizers like urea fertilizer to work effectively, ensuring sustainable agricultural productivity.
8. Railway Ballast Coating
Coating ballast with bitumen prevents weed growth and water penetration. This strengthens the railway track structure. It also reduces maintenance needs over time. Bitumen’s adhesive quality enhances overall stability.
Bitumen Grade 80/100 Meaning and Properties
Bitumen grade 80/100 is a penetration-grade paving bitumen known for its balanced hardness and flexibility. The numbers 80/100 indicate the depth (in tenths of a millimeter) a needle penetrates the bitumen at 25°C under standardized conditions.
This grade is ideal for moderate climates, offering durability in heat and flexibility in cold conditions. It bonds well with aggregates, making it suitable for asphalt mixtures in road construction. Thanks to its stable performance, iranpetroexport recommends grade 80/100 for highways and urban roads where long-term resistance is required.
