Polymer Modified Bitumen
PMB 25/55-65
Petra Oil’s PMB 25/55-65 is an advanced polymer-modified bitumen designed to meet the needs of high-traffic highways, airport runways, and other high-load infrastructure projects. With exceptional resistance to thermal cracking and aging, this product provides long-term durability for pavement surfaces exposed to intense and fluctuating environmental conditions.
Key Specifications:
- Penetration Grade: 25/55
- Softening Point: 65°C
- Standard Compliance: IS 15462:2019
- Type: Polymer Modified Bitumen (PMB)
Main Applications of PMB 25/55-65:
- Highways and Expressways: Ideal for high-performance highways with heavy truck and vehicle traffic. It offers a highly durable asphalt binder that resists rutting and cracking.
- Airport Runways: Withstanding high and low temperatures, PMB 25/55-65 ensures excellent performance on airport runways where durability and temperature stability are critical.
- Industrial Roads: Designed for industrial areas and heavy-duty roads that endure frequent exposure to heavy vehicles and equipment, providing high flexibility and resistance to damage.
Benefits of PMB 25/55-65:
- Provides high resistance to cracking and moisture damage.
- Long-lasting durability in fluctuating temperatures.
- Reduced maintenance costs due to superior resilience.
