Description:
Polymer Modified Bitumen (PMB) is an advanced type of bitumen enhanced with polymers to improve its elasticity, durability, and resistance to extreme weather conditions. It offers superior performance compared to conventional bitumen, making it ideal for high-traffic roads, highways, airports, and bridge decks. The addition of polymers significantly enhances the bitumen’s resistance to cracking, rutting, and aging, ensuring a longer service life for pavements.
PMB provides excellent adhesion, flexibility, and resilience, even under heavy loads and fluctuating temperatures. Its improved viscoelastic properties make it the preferred choice for infrastructure projects requiring superior performance and longevity.
Available Grades:
- PMB 40 (High elasticity for heavy-duty roads and highways)
- PMB 70 (Enhanced durability for moderate to high traffic conditions)
- PMB 120 (Flexible and fatigue-resistant for extreme climate conditions)
- Custom Grades Available on Request
Specifications:
- Softening Point: ≥ 60°C
- Penetration at 25°C: 40-100 dmm (depending on grade)
- Elastic Recovery at 25°C: ≥ 60%
- Viscosity at 135°C: 1000-3000 cSt
- Flash Point: ≥ 230°C
- Standard Compliance: ASTM D5976, IS 15462
Applications:
- Highways & Expressways: Increased durability for heavy traffic loads.
- Airport Runways: Ensures resistance to extreme pressure and temperature changes.
- Bridges & Flyovers: Enhanced flexibility and waterproofing properties.
- Urban Roads & Heavy-Duty Pavements: Reduces maintenance costs and extends service life.
Polymer Modified Bitumen is the ultimate solution for modern infrastructure, delivering unmatched performance, longevity, and resistance to environmental stresses. Its advanced formulation makes it a sustainable and cost-effective choice for high-quality road construction and maintenance projects.
