Performance That Matches Your Road Needs

Not all roads face extreme heat or intense pressure. However, many still require a binder that offers flexibility, strength, and longevity. That’s where PMB 25/70 comes in. This performance-grade polymer modified bitumen gives pavements extra durability without overengineering for milder environments.

Moreover, it reduces cracking and fatigue while maintaining surface quality. With excellent rutting resistance and adhesion, 25/70 becomes a practical and cost-effective solution for national and regional roads.

What Is PMB 25/70?

PMB 25/70 refers to Polymer Modified Bitumen with a penetration value of approximately 25 dmm and a softening point around 70°C. In other words, this grade strikes a balance between flexibility and stiffness—suitable for environments with changing temperatures.

Because it contains elastomeric polymers, polymer modified bitumen 25/70 offers stronger performance than regular bitumen in terms of durability and resistance to thermal stress.

Why Choose PMB 25/70? 

There are several reasons contractors prefer pmb25/70 over traditional binders, First, it’s engineered to handle a wide range of temperature and load conditions. Second, it extends pavement life.

  • Enhanced flexibility in moderate climates

  • Reduced rutting and cracking

  • Improved fatigue resistance under traffic loads

  • Strong bond with aggregates

  • Fewer maintenance cycles

As a result, roads made with this binder stay smoother and stronger longer.

Common Applications of PMB 25/70

Thanks to its thermal flexibility and consistent bonding, this grade is widely used in infrastructure projects. For example:

  • Urban intersections – Withstands stop-and-go movement

  • Secondary roads and bypasses – Handles regional traffic loads

  • Bridge decks – Adapts to vibration and structural shifts

  • Commercial lots and depots – Carries light industrial loads

  • Four-season roads – Resists thermal contraction and expansion

Consequently, this binder helps planners and contractors deliver roads that meet local climate needs and budget goals.

Clearly, pmb 25/70 offers longer-lasting value in moderate-to-variable climates.

Mixing and Application 

Fortunately, contractors can use 25/70 with standard hot-mix asphalt plants. It blends well with common aggregates and works with existing equipment.

In addition, proper heating and agitation ensure consistent performance on-site.

Cost Benefits and Lifecycle Savings

Although its initial price is slightly higher than unmodified bitumen, polymer modified bitumen 25/70 reduces total project cost over time. This is because it decreases the need for frequent maintenance and resurfacing.

Moreover, smoother roads reduce vehicle wear and user complaints—an important advantage for municipalities and public agencies.

What does 25/70 mean?

“25” is the penetration grade (softness), and “70” is the softening point (heat resistance). Together, they define the binder’s ideal use conditions.

Yes. It performs well in both mild and moderately cold or warm regions. As a result, it’s versatile across most geographic zones.

No, you don’t. Standard hot-mix asphalt plants work fine. However, follow recommended temperatures and stir properly.
