PMB 90/150 Polymer Modified Bitumen Supplier and Exporter

PMB 90/150 is a soft, highly elastic grade in the Tiger Bitumen range of Polymer Modified Bitumen. It has a penetration range of 90 to 150 tenths of a millimetre (0.1 mm) at 25 °C. Compared with PMB 65/105, this grade has a softer consistency. Depending on its formulation, the elastomeric polymer can improve flexibility and elastic recovery. As a result, the binder may suit asphalt surfacings in cold climates and pavements that need to accommodate movement without cracking.

Key Characteristics and Benefits

• Soft, high-penetration binder: Its penetration range of 90–150 (0.1 mm at 25 °C) provides a relatively soft consistency.
• Low-temperature flexibility: The soft binder and polymer system may help maintain flexibility in cold conditions. Actual performance depends on the formulation and declared specification.
• Elastic recovery: The elastomeric polymer can help the binder stretch and recover as traffic loads and pavement movement place it under strain.
• Strain accommodation: In a suitable pavement design, the binder may help surfacing accommodate movement caused by variable foundation conditions or frost-related effects.
• Controlled working temperatures: Mixing and laying temperatures vary by product. Therefore, follow the supplier’s technical data sheet and approved mix design.

Applications

• Asphalt wearing courses in cold climates, where the approved specification permits
• Flexible surfacings on roads affected by frost heave or variable bearing capacity
• Low- to medium-traffic roads where crack resistance is a key design requirement
• Thin asphalt layers that require high binder flexibility
• Binder for polymer-modified bitumen emulsions when the formulation is suitable

Choosing the Right Grade

This softer binder may be suitable when low-temperature flexibility and resistance to cracking under strain are priorities. However, engineers should also consider traffic loading, climate, pavement structure and the required performance class before selecting a grade.

Where a project needs a firmer binder, PMB 75/130 or PMB 65/105 may be worth evaluating if their specifications meet the design requirements. For applications requiring a harder grade, PMB 45/80 may also be considered. Ultimately, the approved specification and asphalt mix design should determine the selection. Share your project requirements with your enquiry so the 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 90/150 designation identifies the penetration range at 25 °C, measured according to EN 1426.

The full designation also includes a softening-point class measured using the Ring and Ball method under EN 1427. The reference designations supplied for this grade include PMB 90/150-60 and PMB 90/150-75. Their suffixes indicate the respective minimum softening-point classes.

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. Confirm the complete designation and test values against the technical data sheet for the actual supply.
