Polymer Modified Bitumen Class A-E2

PMB A-E2 is a high-quality modified bitumen made for hot and desert climates with heavy traffic. It contains special polymers that improve its flexibility, strength, and heat resistance. As a result, it stays strong and does not deform, crack, or rut even under high temperatures and heavy loads. With a softening point of 65–85 °C and elastic recovery above 60%, it offers great durability and stability. Therefore, Bitumen A-E2 is an ideal choice for roads and highways in hot regions where both heat and heavy traffic demand strong performance.

Climate Suitability

• Performs perfectly in hot, arid, and desert climates such as the Gulf region, North Africa, and South Asia.

• Withstands surface temperatures above 45 °C without bleeding or softening.

• Maintains stable performance through long, dry summers and heavy daytime loads.

• Suitable for regions where traditional bitumen fails due to heat-induced deformation.

Advantages & Benefits of PMB A-E2

1. High-Temperature Stability:
   The high softening point prevents rutting, shoving, and bleeding, ensuring a smooth and long-lasting surface.

2. Superior Elasticity:
   Elastic recovery above 60 % allows pavements to flex under load without cracking.

3. Enhanced Fatigue Resistance:
   The binder retains strength under repeated traffic stress, extending pavement life.

4. Excellent Adhesion:
   PMB A-E2 adheres firmly to aggregates, reducing stripping and water damage.

5. Ageing Resistance:
   Maintains flexibility and bond even after prolonged exposure to oxidation and UV radiation.

6. Economical Durability:
   Though premium in quality, its extended lifespan cuts maintenance and rehabilitation costs.

Typical Applications

• National highways and expressways

• Heavy-duty industrial pavements and container yards

• Airport runways, taxiways, and aprons

• Bus corridors, logistics zones, and port roads

• Bridge decks and SMA (Stone Mastic Asphalt) surfaces

Its strong elasticity and high viscosity make it ideal for high-stress zones where both heavy loads and extreme heat challenge pavement stability.

Difference Between PMB A-E2 and Penetration Grade Bitumen

PMB A-E2 is stronger and more flexible than normal penetration grade bitumen. While penetration bitumen comes straight from the refinery, PMB A-E2 is mixed with special polymers that make it more elastic and stable in heat. Because of this, it keeps its shape better under heavy traffic and high temperatures, while regular bitumen can soften and form ruts. PMB A-E2 also lasts longer because it resists ageing and cracking. In short, it gives better performance, longer life, and higher resistance to heat—making it a smarter choice for highways, airports, and other busy roads.

Usage & Packing of PMB A-E2

Usage Guidelines:

• Mixing Temperature: 165 – 175 °C

• Compaction Temperature: 150 – 160 °C

• Storage Temperature: ≤ 180 °C (short term)
  Stir the product before use to ensure uniform consistency.

Packing Options:

• 200 kg new steel drums

• 1 MT jumbo bags with poly liner

• Bulk shipments in bitutainers or tankers

Store in a cool, shaded place away from direct sunlight.

Conclusion

Bitumen A-E2 delivers unmatched stability and elasticity in extreme heat. It resists rutting, maintains adhesion, and extends pavement life—making it the best choice for highways, airports, and heavy-duty roads in hot regions. With proven test performance and flexible packing options, PMB A-E2 is a top-tier binder for modern infrastructure projects.
