PMB 45/80 Supplier and Exporter

Looking for a reliable PMB 45/80 supplier in Dubai, UAE? PMB 45/80 is a mid-range Polymer Modified Bitumen used in asphalt paving when a project specification calls for a modified binder with moderate penetration. We serve contractors, traders, and project owners across the UAE and export markets. We prepare each offer against the buyer’s requirements and confirm availability at the quotation stage.

This page explains the PMB 45/80 penetration range, its potential paving applications, and the details to check before ordering. For an overview of all nine ranges, visit our Polymer Modified Bitumen category.

What Does PMB 45/80 Mean?

PMB stands for Polymer Modified Bitumen. Manufacturers blend bitumen with a polymer to modify its performance across temperatures and under traffic. The 45/80 designation refers to the nominal penetration range. At 25 °C, a standard needle penetrates the binder by 45 to 80 tenths of a millimeter under the specified test conditions.

A Mid-Range Penetration Band

Penetration indicates consistency. PMB 45/80 therefore sits between harder ranges, such as 10/40 and 25/55, and softer ranges, such as 75/130. However, penetration bands can overlap. For example, a result of 50 may fall within the nominal ranges of 25/55, 45/80 and 40/100. Buyers should therefore check the complete product specification rather than choose a binder from its penetration range alone.

Why the Range Is Not the Full Picture

Other properties also affect how a PMB performs in service. These include softening point, elastic recovery and cohesion. The base bitumen, polymer and formulation influence those properties. The applicable product specification and Technical Data Sheet (TDS) state the required values; the 45/80 label does not establish them on its own.

PMB 45/80 Characteristics

The following points describe PMB 45/80 in general terms. Actual test values depend on the formulation and project requirements. Review the offered product’s TDS for measured results.

Moderate Consistency

Compared with harder PMB ranges, a 45/80 binder has a broader, mid-range penetration band. Specifiers may consider this range when a project calls for polymer modification without selecting one of the hardest penetration ranges. The complete specification should still determine suitability.

What Polymer Modification Adds

Compared with unmodified bitumen of similar penetration, polymer modification can improve cohesion and elastic response and reduce temperature sensitivity. Depending on the formulation and asphalt mix design, these properties may help a pavement resist rutting in hot weather and cracking under repeated loading.

Relevance to Hot Climates

Roads in the UAE and Gulf region can experience high pavement temperatures during summer. However, penetration alone cannot confirm whether PMB 45/80 suits a particular site. The specifier should review the full binder specification, especially the softening-point requirement, alongside traffic conditions and pavement design.

Checks Before Specifying

Follow the offered product’s TDS for handling, workability, and compaction guidance. In addition, the mix designer should confirm that the binder works with the proposed asphalt mix and intended pavement layer.

PMB 45/80 Applications

Project teams may consider a mid-range PMB for asphalt layers that require modification but do not call for the hardest available range. Depending on the specification, climate, traffic and mix design, PMB 45/80 may suit:

• Wearing courses on main roads, arterial roads and highways with moderate to heavy traffic
• Resurfacing and overlay work on existing pavements
• Stone mastic asphalt and thin surfacing systems where binder cohesion matters
• Road networks exposed to substantial daily or seasonal temperature changes
• Infrastructure projects that specify a modified binder with moderate consistency

Nevertheless, PMB 45/80 is not the default choice for every project. A heavily loaded road or a site with demanding pavement temperatures may require a harder range. Conversely, certain surfacing systems or project conditions may call for a softer range. Always follow the project’s approved binder specification.

PMB 45/80 and EN 14023

EN 14023 provides a European framework for specifying Polymer Modified Bitumen. It defines properties for testing and classifies results into performance classes. The relevant national or project specification then selects the required combination of classes.

Within this framework, 45/80 identifies the penetration range, not the complete product designation. A full designation also includes the applicable softening-point class and may specify additional properties, such as elastic recovery or cohesion. Since different PMB formulations can share the same penetration range, do not treat 45/80 alone as a complete EN 14023 designation.

Before ordering, compare the full designation with your project documents. The quotation and TDS should confirm the specification that applies to the offered PMB 45/80 product.

The GCC Standardization Organization has adopted EN 14023 as a Gulf standard. However, individual authorities and projects may define binder requirements differently, including through Performance Grade (PG) systems. If your tender uses PG terminology, see our Performance Grade (PG) bitumen page.

PMB 45/80 vs Conventional Penetration Bitumen

Conventional, unmodified penetration bitumen is classified chiefly by penetration. You can learn more on our Penetration Bitumen page. PMB 45/80 also uses a penetration range, but polymer modification targets properties that penetration classification alone does not describe.

This difference matters to buyers for three reasons. First, a project specifier must approve any substitution between the two binder types. Second, matching penetration figures do not guarantee matching performance. Finally, PMB is not automatically the most suitable or economical option. Conventional bitumen can perform well when it meets the project’s requirements.

Choosing PMB 45/80 for a Project

The project specification normally identifies the required binder range. If it does not, or if the tender permits alternatives, review the following factors before selecting PMB 45/80.

The project requirements must determine the final grade and complete classification. If a harder or softer range may be more suitable, compare the available options in our PMB category, which presents all nine ranges together.

PMB 45/80 Supply from Dubai

As a PMB 45/80 supplier serving Dubai, the UAE, and export markets, we build each quotation around the buyer’s specification and delivery destination. Contractors, local buyers and international importers can share their requirements for review.

For UAE projects, provide the binder clause from the tender or consultant documents. For export orders, also identify the destination, preferred delivery terms, and required shipping or import documents. We confirm availability, product origin, and loading port in writing in the quotation rather than assuming these details in advance.

PMB 45/80 Documentation

We confirm the available documentation according to the product and order requirements. A typical PMB 45/80 document set may include:
