Tiger Bitumen supplies PMB 25/55, a Polymer Modified Bitumen within the EN 14023 nominal penetration range framework, for international road, highway and heavy-traffic pavement projects. PMB 25/55 is supplied according to the complete designation and standard specified for each project.

What Is PMB 25/55?

PMB 25/55 refers to Polymer Modified Bitumen with a nominal penetration range of 25 to 55 (0.1 mm) at 25°C. Bitumen in this range is modified with a polymer to increase stiffness and resistance to permanent deformation while retaining the flexibility needed for demanding, heavy-traffic pavements.

PMB 25/55 and EN 14023 Designation

Under EN 14023, 25/55 is a nominal penetration range rather than a complete grade designation on its own. A complete PMB designation combines this penetration range with the applicable minimum softening-point class specified for the project. The applicable softening-point class for PMB 25/55 is confirmed against the project specification and quotation requirements.

PMB 25/55 Specification Parameters

The penetration range is fixed by the 25/55 designation. The applicable softening-point class and declared performance properties depend on the complete EN 14023 designation and project specification. The exact designation and applicable values are confirmed against the customer’s project requirements at the quotation stage.

PMB 25/55 Applications

Internationally, the 25/55 penetration range is generally associated with heavy-traffic asphalt mixtures requiring resistance to permanent deformation and fatigue cracking, including highways, airport pavements and other high-load applications, where a stiff but still flexible binder is required. Exact application suitability should be confirmed against the complete designation and the project’s specification.

Packaging and Export Supply

PMB 25/55 is supplied primarily in new steel drums. Where a project specifically requires bag packaging, PMB 25/55 can also be supplied in 1 Metric Ton (1,000 kg) PP woven bags in a steel cage, subject to confirmation for the specific grade and order. Tiger Bitumen’s packaging facility is located in the Karachi Export Processing Zone, close to Port Qasim and Karachi Port, supporting container export through Pakistan’s major ports. See our drum and jumbo bag packing page for details.

TDS, COA and Inspection

Tiger provides a PMB 25/55-specific Technical Data Sheet and a shipment-specific Certificate of Analysis matched to the confirmed grade and project specification. Third-party inspection through SGS or Bureau Veritas can be arranged where required by the buyer or project.

Why Source PMB 25/55 from Tiger Bitumen

Tiger Bitumen is expanding its product range to offer PMB across the full EN 14023 nominal penetration range, including PMB 25/55, supplied according to each project’s specification. Export operations are based in the Karachi Export Processing Zone, with direct access to Port Qasim and Karachi Port for international shipments, and shipments can be arranged for third-party inspection through SGS or Bureau Veritas. Lead time and available quantity for PMB 25/55 are confirmed at the quotation stage. See our full Polymer Modified Bitumen (PMB) range or read more about Tiger Bitumen.
