Polymer Modified Bitumen (PMB) – High-Performance Export Grade — Export from Iran
Polymer Modified Bitumen (PMB) is a high-performance binder produced by blending base bitumen with special polymers (such as SBS, SBR, or EVA). This modification significantly enhances elasticity, flexibility, fatigue resistance, and long-term durability, making it ideal for heavy-duty and high-stress road applications.
We supply premium Polymer Modified Bitumen from advanced blending facilities in Iran, manufactured under strict quality control and in full compliance with ASTM D6373, EN 14023, and Superpave PG specifications. Ideal for modern infrastructure projects in extreme climates.
Note: PG grading (e.g., PG76-28) indicates high-temperature rutting resistance (76°C) and low-temperature cracking resistance (-28°C). Polymer modification improves both performance and lifespan.
🛣️ Janis Group PMB Capability: We supply advanced Polymer Modified Bitumen (PMB) directly from state-of-the-art Iranian blending facilities. Using premium SBS/SBR polymers, we deliver precise Superpave PG grades with guaranteed elastic recovery and polymer dispersion. Every shipment undergoes rigorous DSR and BBR testing via SGS inspection, ensuring maximum rutting and cracking resistance for global highway and airport projects.

Applications
- High-Traffic Highways: Expressways and toll roads requiring maximum durability
- Airport Infrastructure: Runways and taxiways subjected to extreme static and dynamic loads
- Bridge Decks: Expansion joints and waterproofing membranes
- Urban Overlay: Surface dressing and rehabilitation of aging road networks
- Extreme Climates: Regions with severe temperature variations (hot summers, freezing winters)
- Heavy-Duty Pavements: Industrial zones, ports, and logistics hubs
Which PMB Grade Fits Your Project Conditions?
PG70-28 (Wide Temp. Range)
Key Strength: Exceptional low-temperature cracking resistance down to -28°C.
Choose this if: Your project is in a region with harsh winters and moderate summers, requiring protection against thermal fatigue.
Typical buyers: Road authorities in temperate/cold regions, mountainous highway contractors.
PG76-22 / PG76-28 (Heavy Duty)
Key Strength: Superior rutting resistance under heavy loads and high ambient temperatures.
Choose this if: You are building major expressways, ports, or roads in hot climates where standard binders would permanently deform.
Typical buyers: National highway departments, Middle East/Africa infrastructure projects, airport contractors.
PG82-10 (Ultra Heavy Duty)
Key Strength: Maximum high-temperature stability (up to 82°C) for the most demanding environments.
Choose this if: Your project involves airport runways, extreme desert heat, or heavily loaded industrial pavements.
Typical buyers: Aviation authorities, specialized highway contractors, heavy industrial zone developers.
Key Notes
- Polymer Type: Typically SBS (Styrene-Butadiene-Styrene) for optimal elasticity and durability.
- Elastic Recovery: Measures the bitumen’s ability to return to its original shape after stress — a key indicator of modification quality.
- High-Temp Performance: Resists rutting and deformation under heavy traffic and high temperatures.
- Low-Temp Performance: Prevents thermal cracking in cold climates.
- All batches are tested for polymer dispersion and storage stability.
- Pre-shipment inspection by SGS is included for every shipment.
Frequently Asked Questions (FAQ)
PMB is blended with polymers like SBS, significantly enhancing elasticity, fatigue resistance, and temperature susceptibility. It resists rutting in extreme heat and thermal cracking in cold climates, extending pavement lifespan by 2–3 times.
The first number (76) is the maximum average 7-day pavement temperature (°C) for rutting resistance. The second number (-28) is the minimum pavement temperature (°C) for thermal cracking resistance.
We primarily use SBS (Styrene-Butadiene-Styrene) for optimal elasticity and durability, though SBR and EVA modifications are available upon specific project request.
Minimum order is 200 MT per shipment, supplied in bulk heated tankers, flexi-bags (18–22 MT per 20ft container), jumbo bags, or steel drums.
PMB’s superior elastic recovery prevents permanent deformation (rutting) under heavy traffic. Its enhanced flexibility also prevents reflective and thermal cracking, significantly reducing maintenance costs.
