PMB 45/80 Exporter and Supplier from Brazil
Versatile Polymer Modified Bitumen for Wearing Courses, SMA and Porous Asphalt
Brazil Bitumen, powered by Tiger Bitumen (HY International Group), serves international importers, distributors, asphalt producers and road contractors seeking a PMB 45/80 supplier from Brazil. PMB 45/80 is a polymer modified bitumen grade considered for a range of asphalt surfacing applications, including wearing courses and stone mastic asphalt (SMA), when it meets the project specification. Buyers can explore our Polymer Modified Bitumen range to compare related grades.
This grade combines a nominal penetration range of 45 to 80 with a specified softening-point class and other performance requirements. As a result, it can offer a balance of deformation resistance and flexibility, depending on its full designation and formulation.
Each quotation should identify the complete product designation, applicable test methods and specification limits. Buyers can then compare the technical data sheet and shipment-specific certificate of analysis with their project requirements before placing an order.
What is PMB 45/80?
PMB 45/80 is a polymer modified bitumen designation used within the EN 14023 framework. The figures 45/80 refer to a nominal penetration range of 45 to 80 tenths of a millimetre at 25 °C. This places the grade between harder grades, such as PMB 25/55, and softer grades, such as PMB 65/105, when comparing their nominal penetration ranges.
The penetration range alone does not define the complete grade. For example, designations may include PMB 45/80-50, PMB 45/80-55, PMB 45/80-60 or PMB 45/80-65, depending on the applicable specification. The number after the hyphen identifies the relevant minimum softening-point class in degrees Celsius. Therefore, buyers should confirm the exact designation required by the project.
PMB may use elastomeric polymers such as SBS, but the polymer type and modification method should not be assumed from the grade name alone. These details, together with elastic recovery and other required properties, should be confirmed in the technical data sheet for the product being offered.
PMB 45/80 Technical Specifications
The following table summarises properties commonly reviewed when specifying PMB 45/80 under the EN 14023 framework. However, the exact limits depend on the full designation and applicable specification. The confirmed values for the product offered by Brazil Bitumen should be stated in its technical data sheet and shipment-specific certificate of analysis.

Brazilian specifications: In Brazil, elastomer-modified asphalts include types such as 55/75-E, 60/85-E and 65/90-E under ANP Resolution No. 897/2022. These types have defined requirements, including penetration limits, softening point and elastic recovery. Therefore, PMB 45/80 is not automatically equivalent to any of these Brazilian types. Buyers supplying Brazilian projects should compare the full technical data sheet with the applicable ANP, DNIT or project specification.
Applications of PMB 45/80
PMB 45/80 is considered for a range of pavement layers where the specified binder properties suit the traffic, climate and mix design. Typical applications include:
- Asphalt concrete wearing courses on highways, urban roads and main roads
- Stone mastic asphalt (SMA) surfacing, where the project specification permits this grade
- Porous asphalt and open-graded friction courses, when the selected softening-point and performance classes are suitable
- Binder courses that require a medium-consistency modified binder
- Thin hot-mix surfacing and stress-absorbing membrane interlayers (SAMI), where specified
- Airport pavements, bridge-deck surfacing and bus corridors, subject to the applicable project requirements
However, not every PMB 45/80 designation is suitable for every application. The pavement designer should select the complete grade based on the project specification, mix design, traffic loading and expected service temperatures.
Key Features and Benefits
When the complete grade is correctly specified and used in a suitable mix design, PMB 45/80 can offer several potential benefits:
- Balanced binder properties: the specified grade can help balance deformation resistance and flexibility.
- Elastic recovery: where the binder meets the required recovery class, it can recover after deformation caused by loading.
- Resistance to fatigue: appropriate polymer modification can improve resistance to fatigue-related distress compared with a suitable unmodified reference binder.
- Aggregate retention: the required cohesion and binder properties can support aggregate retention in suitable SMA and porous asphalt mixtures.
- Versatile applications: depending on its complete designation, the grade may be considered for different asphalt layers and surfacing systems.
Nevertheless, actual pavement performance depends on binder properties, aggregate quality, mix design, construction methods, climate and traffic. Therefore, the project specification and verified technical data should guide product selection.
Handling, Packaging and Documentation
PMB 45/80 should be stored, transported and mixed according to the supplied product’s technical data sheet. Depending on the formulation, temperature control and suitable storage conditions may be required to maintain binder homogeneity. For this reason, avoid prolonged storage at high temperatures and follow the manufacturer’s handling instructions.
Packaging options should be confirmed with each quotation. For details about available formats, see our bitumen drum packing page.
Depending on the order and agreed inspection requirements, the export documentation may include:
- Technical data sheet for the offered PMB 45/80 grade
- Certificate of analysis for the supplied batch
- Safety data sheet
- Independent inspection by SGS or Bureau Veritas, if arranged and agreed
- Standard export documents, including commercial invoice, packing list, bill of lading and certificate of origin, as applicable
Before ordering, buyers should confirm the complete grade designation, required quantity, packaging, destination port, delivery terms and any project-specific inspection or documentation requirements.

PMB 45/80 FAQs
PMB 45/80 is a polymer modified bitumen with a penetration range of 45 to 80 tenths of a millimetre at 25 °C, named under the EN 14023 framework. It is a medium-consistency grade and one of the most widely used PMB grades.
The number after the hyphen is the minimum softening point in °C. Higher classes generally indicate a more highly modified binder, often specified for porous asphalt and demanding surfacing. The class of our offered product is stated in its technical data sheet.
It is typically used in wearing courses, SMA and porous asphalt on highways and urban roads. It is also used in some binder courses, thin surfacing and stress-absorbing interlayers.
Yes. PMB 45/80 is commonly specified for porous and open-graded asphalt, usually in a higher softening point class. The grade and class should follow the project specification.
PMB 25/55 is harder and is chosen where maximum rutting resistance is the priority. PMB 45/80 is softer and more flexible, making it suitable for a wider range of surface layers.
Not automatically. Brazilian types are defined under ANP Resolution No. 897/2022 with their own softening point, elastic recovery and penetration limits. Compliance should be checked against our technical data sheet.
We supply a technical data sheet, certificate of analysis, safety data sheet and standard export documents. SGS or Bureau Veritas inspection can be arranged on request.
