PMB 40/100 Polymer Modified Bitumen Supplier and Exporter

PMB 40/100 is a polymer-modified bitumen grade in the Tiger Bitumen range of Polymer Modified Bitumen. It has a penetration range of 40 to 100 tenths of a millimetre (0.1 mm) at 25 °C. This range offers flexibility across different pavement applications, while polymer modification can improve elasticity, cohesion and temperature-related performance. Engineers may specify this binder for hot-mix asphalt wearing, binder and base courses on roads, airfields and other paved areas, depending on the project requirements.

Key Characteristics and Benefits

• Broad penetration range: The 40–100 (0.1 mm at 25 °C) range covers medium-to-soft consistencies. Therefore, it may suit different pavement layers and climate conditions when the complete specification supports its use.
• Rutting and cracking performance: Polymer modification can improve elastic behaviour and high-temperature performance. The selected formulation and asphalt mix design determine how well the pavement resists permanent deformation and cracking.
• Elasticity and fatigue resistance: Suitable polymer systems can improve elastic recovery and binder cohesion. These properties help asphalt withstand repeated traffic loading.
• Ageing resistance: The applicable specification sets limits for changes in binder properties after ageing. Check the product’s declared test results to confirm compliance with project requirements.
• Controlled working temperatures: Mixing and compaction temperatures depend on the formulation. Always follow the supplier’s technical data sheet and approved mix design.

Applications

• Wearing courses on heavily trafficked roads, including stone mastic asphalt and thin surfacing where specified
• Binder and base courses that require an elastic binder under the applicable specification
• Asphalt mixtures for airfields and other paved areas
• Pavements exposed to wide seasonal temperature variations
• Anti-cracking and reinforcement layers where the approved design requires enhanced elasticity

Selecting the Right Grade

This grade may suit projects that require an elastic binder across a broad penetration range. However, engineers should consider traffic loading, pavement structure, climate and the approved asphalt mix design before choosing a grade.

Where a project prioritises stiffness and rutting resistance in base or binder layers, a harder grade such as PMB 25/55 may be worth evaluating. Alternatively, PMB 45/80 offers a different penetration range for projects whose specifications call for that grade. Include your required 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 for roads, airfields and other paved areas. The 40/100 designation identifies the penetration range at 25 °C, measured according to EN 1426.

The full grade designation also includes a softening-point class measured using the Ring and Ball method under EN 1427. Examples include PMB 40/100-65 and PMB 40/100-75. The suffix indicates the applicable minimum softening-point class, but it does not define every performance property of the binder.

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