PMB 75/130 Polymer Modified Bitumen Supplier and Exporter

PMB 75/130 is a soft, highly elastic grade in the Tiger Bitumen range of Polymer Modified Bitumen. Its penetration range is 75 to 130 tenths of a millimetre (0.1 mm) at 25 °C. Compared with PMB 65/105, it has a softer consistency. Depending on its formulation, polymer modification can improve elasticity, toughness and cohesion. As a result, this grade may suit anti-cracking layers, stress-absorbing membranes and selected surface treatments.

Key Characteristics and Benefits

• Soft, high-penetration binder: Its penetration range of 75–130 (0.1 mm at 25 °C) provides a relatively soft consistency.
• High toughness and elasticity: The polymer system can improve elastic recovery and cohesion, helping the binder accommodate movement.
• Reflective crack resistance: When used in a suitable pavement design, its flexibility can help absorb stresses from cracked or jointed layers below.
• Low-temperature flexibility: Its softer consistency may help maintain flexibility in colder conditions, depending on the formulation and declared performance.
• Controlled working temperatures: Mixing and application temperatures vary by product. Therefore, follow the supplier’s technical data sheet and approved mix design.

Applications

• Anti-cracking asphalt mortars and interlayers
• Stress-absorbing membranes and interlayers (SAM and SAMI)
• Crack-prevention systems using non-woven geotextiles
• Selected high-quality surface treatments
• Manufacture of polymer-modified bitumen emulsions where the formulation is suitable

Choosing the Right Grade

This softer grade may be appropriate when flexibility and crack resistance are priorities, particularly in anti-cracking layers, membranes and surface treatments. However, the final selection should also account for traffic loading, climate, pavement structure and the project specification.

For applications that require a firmer binder, PMB 65/105 or the harder PMB 45/80 may be worth evaluating. However, the approved mix design and required performance class should determine the final choice. Include your project specification in your enquiry so our team can confirm suitability.

Technical Specifications and EN 14023

EN 14023 provides a framework for specifying polymer-modified bitumen used on roads, airfields and other paved areas. The 75/130 designation identifies the penetration range at 25 °C, measured according to EN 1426.

The full designation also includes a softening-point class determined using the Ring and Ball method under EN 1427. One designation used for this grade is PMB 75/130-60, where the suffix indicates a minimum softening point of 60 °C.

Other properties, including cohesion, resistance to hardening, Fraass breaking point, elastic recovery and storage stability, depend on the applicable specification class and declared product performance. Therefore, confirm the complete designation and test values against the technical data sheet for the actual supply.
