PMB 10/40 Polymer Modified Bitumen Supplier and Exporter

PMB 10/40 is the hardest grade in the Tiger Bitumen range of Polymer Modified Bitumen. Its penetration range is 10 to 40 tenths of a millimetre (0.1 mm) at 25°C. This low-penetration binder combines high stiffness with the cohesion and elasticity that polymer modification can provide. Engineers may use it in hot-mix asphalt when pavement designs require a stiff binder for demanding traffic conditions, including high-modulus base and binder courses on heavily loaded roads.

Key Characteristics of PMB 10/40

• Hard, low-penetration binder: Its penetration range of 10–40 (0.1 mm at 25°C) identifies it as a hard binder within the PMB range.
• Resistance to permanent deformation: Its stiffness can help asphalt resist rutting under heavy, slow-moving loads and high pavement temperatures when the formulation suits the application.
• Polymer-enhanced cohesion and fatigue resistance: Depending on the polymer system, modification can improve cohesion, elastic recovery and resistance to fatigue cracking compared with the unmodified base binder.
• Working temperatures: Hard grades may require different mixing and compaction temperatures from softer grades. Therefore, follow the temperatures stated in the product data sheet.

Applications of PMB 10/40

• High-modulus asphalt base and binder courses for heavy-duty pavements
• Highways and urban roads carrying heavy traffic, particularly in hot climates where the project specification supports its use
• Areas with slow-moving or stationary heavy loads, such as container terminals, port yards, bus stations, truck lanes, toll plazas and industrial hardstandings
• Asphalt layers where the project specification calls for a suitable hard polymer-modified binder

Selecting PMB 10/40 for Your Project

Engineers may choose this grade when stiffness and resistance to rutting are important, particularly in hot climates, under heavy axle loads and in structural asphalt layers. However, a harder binder is not automatically the best choice for every pavement.

Where flexibility at lower temperatures or in thin surfacing layers matters more, a softer grade such as PMB 25/55 or PMB 45/80 may be more suitable. The project specification, climate, traffic conditions and asphalt mix design should determine the final grade.

Tiger Brand Polymer Modified Bitumen PMB 10/40 Specifications

EN 14023 provides a specification framework for polymer-modified bitumen used on roads, airfields and other paved areas. The 10/40 designation identifies the penetration range at 25°C, measured according to EN 1426. However, this range alone does not represent the complete product designation.

The full designation also includes the applicable minimum Ring and Ball softening-point class, measured according to EN 1427. Examples of designations used for this grade include PMB 10/40-65 and PMB 10/40-70. The applicable designation depends on the product’s declared properties and specification.

Other properties, including cohesion, resistance to hardening, flash point and, where required, Fraass breaking point, elastic recovery and storage stability, depend on the applicable EN 14023 requirements. Therefore, confirm the complete grade designation and test values against the product-specific technical data sheet.
