The addition of polymers to bitumen modifies its physical and chemical characteristics, making it more robust, resilient, and resistant to temperature fluctuations, rutting, cracking, and aging. PMB is utilized in road building, roofing, waterproofing, and other civil engineering applications.
Styrene-butadiene-styrene (SBS), styrene-butadiene rubber (SBR), ethylene-vinyl acetate (EVA), and polyethylene may change bitumen (PE). Polymer choice relies on PMB characteristics and application.
Polymers increase performance and endurance to bitumen, making it a desirable building material.
Delving into the intriguing journey of Polymer Modified Bitumen, or PMB, we must rewind the clock back to the early 20th century. This was when asphalt material science started making leaps in understanding and practicality. However, the birth of PMB, as we recognize it today, wasn’t until the s when German inventors utilized polymers to enhance the properties of bitumen.
PMB’s existence traces back to the desire to improve bitumen’s durability and resilience, particularly for road construction. This new variant of bitumen, also known as modified bitumen or elastomer modified bitumen, provided a significant increase in performance. It extended the lifespan of roads, reducing maintenance frequency, and proved vital in withstanding diverse climatic conditions.
Progress in the field of PMB was slow yet steady during the mid-20th century. It wasn’t until the s that PMB’s use took a real upswing, especially in Europe. This advancement was due to the commercial production of Styrene-Butadiene-Styrene (SBS) polymers, a critical component in PMB production. The new material provided enhanced elasticity, improved resistance to deformation, and heightened temperature stability.
In the early s, with the development of the Functional Polymer Modified Bitumen (FunPMB), PMB started stepping into an era of sustainable and functional road building. The Functional PMB proved advantageous for their environmental benefits, including reduced emissions during production and installation, and noise reduction for the end-user.
Today, PMB is considered an essential tool in the construction industry, promising sustainability, durability, and superior performance. The journey of PMB reflects our constant pursuit for improvement and innovation, signifying the role of materials science in shaping our infrastructural future.
As we continue to traverse this road, we are equipped with the power of history and the promise of science, driving the evolution of products like PMB. Here’s to paving the way forward with Polymer Modified Bitumen, transforming landscapes and setting new standards in infrastructure development.
Polymer Modified Bitumen, a vital material in construction, particularly in paving and roofing applications, is known by several other names, including:
These names all refer to Bitumen that has been altered by the addition of polymers to enhance its physical properties, including durability, flexibility, and resistance to environmental elements. The specific name used often depends on the type of polymer added or the application the modified bitumen is intended for.
The Harmonized System (HS) Code for Polymer Modified Bitumen falls under the category of , specifically , which comprises bituminous mixtures based on natural asphalt, natural bitumen, petroleum bitumen, mineral tar or mineral tar pitch.
As for its chemical composition, PMB doesn’t have a specific chemical formula due to its complex, varied structure depending on the type of polymer used. However, the chemical formula for bitumen, which is the base material for PMB, is roughly C25H32. The specific structure and formula will change with the addition of polymers.
Likewise, due to the varied nature of the PMB depending on the specific polymer modification, there isn’t a single Chemical Abstracts Service (CAS) number applicable. The CAS number for Bitumen is -42-4. Polymers used, such as APP or SBS, have their own CAS numbers: -07-0 and -55-8 respectively.
Polymer Modified Bitumen (PMB) is a composite material that consists of the following primary components:
Bitumen: Bitumen, also known as asphalt, is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It forms the base of PMB and is the component that provides the initial adhesive and waterproofing characteristics.
Polymers: Polymers are added to the bitumen to improve its physical properties. There are primarily two types of polymers used:
Elastomeric Polymers: These polymers, including Styrene-Butadiene-Styrene (SBS) and Styrene-Butadiene Rubber (SBR), enhance the elastic properties of the bitumen, increasing its flexibility and resilience at both high and low temperatures.
Plastomeric Polymers: These polymers, such as Atactic Polypropylene (APP) and Ethylene Vinyl Acetate (EVA), provide increased rigidity and resistance to aging.
Fillers: Materials like limestone, fly ash, or carbon black may be used as fillers to improve the stiffness and reduce the cost of the PMB.
Additives: Various additives may be incorporated to further enhance the properties of the PMB. These can include antioxidants for improved resistance to aging, adhesion promoters for better bonding with the aggregate in road construction, and fire retardants for increased fire resistance in roofing applications.
Stabilizers: To ensure the polymer doesn’t separate from the bitumen during storage or transport, stabilizers are added.
The specific composition of PMB can vary greatly depending on the intended application, the performance requirements, and the specific manufacturing process used. However, the goal is always to create a product that combines the adhesive and waterproofing properties of bitumen with the enhanced durability, flexibility, and resistance to environmental stresses provided by the polymers.
Characteristics:
Usage and Applications: Given its higher penetration, PMB 120 is likely to be more ductile and flexible, making it suitable for regions with colder climates or applications that require more pliability.
Characteristics:
Usage and Applications: PMB 70 can be considered an intermediate grade in terms of its rigidity and ductility. It could be ideal for temperate regions or applications that require a balance between flexibility and stability.
Characteristics:
Usage and Applications: With its lower penetration and higher softening point, PMB 40 is likely to be the most rigid and stable of the three. It’s suitable for hotter climates or applications where resistance to softening and rutting is crucial.
There are many different ways to classify polymers, including whether they are natural or synthetic, the type of arrangement of monomers, the arrangement of chains, and the method of polymerization. However, from the perspective of the scientific community, the classification of polymers that is most useful is based on how they behave in terms of their applications and temperatures, and this classification is broken down into three subgroups:
These types of polymers are softened by heat and melted by heat and can take the shape of the mold, and by removing the cooled heat, they turn into a solid state, and this cycle can be repeated several times without changing the properties of the polymer. be repeated Polypropylene (PP), polyethylene (PE) and polystyrene (PS) are part of this category.
These are semi-solid polymers that harden due to the application of heat and are no longer soft and meltable, and are destroyed and lose their properties when heated continuously. In fact, if we examine the intermolecular force of these two groups of polymers, thermoplastics have a weak intermolecular force that can change the shape of the polymer by heating, but thermoset polymers have strong crosslinks that allow shaping and reprocessing. They do not exist. Polyester, polyurethane, resins and silicones are examples of this group.
The name elastomer is derived from the combination of two words, elastic polymer. Elastic means to be elastic, which means that when a force or stress is applied to elastomers, they first change their shape, and when the stress is removed, they rearrange their chains and return to their original state. One of the main features of these materials is having a very low glass transition temperature. That is, these materials are soft at low temperatures. (It should be noted that polymers are very hard and brittle below their glass transition temperature). All kinds of rubbers, including butadiene rubber, natural rubber, are members of this group.
In addition to thermoplastic polymers and elastomer polymers, there is also a category of polymers known as thermoplastic elastomers. These thermoplastic elastomers are created by combining two different types of polymers. This is due to the fact that the beneficial characteristics of both groups are combined, resulting in the formation of a copolymer that is capable of making use of the primary and functional characteristics of both groups. For instance, elastomers are unable to melt and would be destroyed if heat is repeatedly applied, but thermoplastics have both the capacity to melt and the property of being plastic. Polyurethane, polyether-polyester copolymer, olefinic copolymer, and styrene block copolymers are the four primary categories of thermoplastic elastomers. Polyurethane is the most common kind. The findings of the final group have shown to be the most successful when combined with bitumen. In a nutshell, the thermoplastic nature of TPE polymers, in addition to their low viscosity at high temperature and their capacity to open up in bitumen, as well as many other important characteristics, have led to this polymer being recognized as the most effective modifier of the properties of bitumen. For instance, the styrene component of SBS polymer, which is a styrene-butadiene-styrene block copolymer and is an elastomer thermoplastic, is of the thermoplastic kind, while the butadiene component is of the elastomer variety.
The temperature at which butadiene rubber (PB) undergoes its glass transition is -70 degrees Celsius, but the temperature at which polystyrene undergoes its glass transition or softening temperature is 100 degrees Celsius. The thermal stability of this material is improved by combining these two polymers, which allows for a wider temperature range at which it can maintain its integrity. The usefulness of using SBS polymer to generate modified polymer bitumen has been shown, making it one of the best polymers, if not the greatest polymer, employed in the industry that produces bitumen and asphalt. Because a portion of it is composed of rubbers, which, thanks to their very low glass transition temperature, increase the performance of bitumen when exposed to low temperatures and throughout the winter.
One of the polymers that has garnered attention in the bitumen and asphalt sector nowadays is polyphosphoric acid. Another one of these polymers is polyethylene glycol. The combination of polyphosphoric acid and bitumen has been the subject of a significant amount of penetration, and the findings have revealed that even a minute quantity of this polymer can boost the softening point of bitumen by ten degrees and reduce the degree to which it can be penetrated by five degrees. Additionally, polyphosphoric acid may be used as a bitumen compatibilizer when combined with other polymers such as rubber powder; however, it is essential to keep in mind that a high-speed mixer is required for this process.
Because the temperature at which bitumen breaks is approximately -10 to -12 degrees, the use of bitumen in areas where the temperature drops below -12 degrees during the winter will cause the bitumen to break and create cracks on the asphalt surface. This is due to the fact that bitumen is both hard and fragile. Because of the usage of rubbers, the temperature at which asphalt will break may be lowered to as low as -30 degrees or even lower. This lowers the temperature at which cracks and other types of asphalt damage can occur during the winter. On the other hand, the addition of this polymer to bitumen causes a rise in the viscosity of the bitumen and a rise in the temperature at which it begins to soften at high temperatures and hot conditions. This helps to prevent the bitumen from becoming loose and rutting in asphalt. In point of fact, one of the reasons why bitumen and asphalt are modified with polymers is in order to make the roadway surface more durable in a variety of climates.
Normal bitumens develop fatigue cracks in a very short amount of time on roads that have a high traffic load; however, the usage of polymer-modified bitumen and asphalt enables us to have longer periods of time. For there to be no cracks in the asphalt and for the coating to be in good condition. Because of this, it is not necessary to apply protective asphalts while stamping and sealing the asphalt surface, which results in savings in both money and energy. When thermoplastics like polyethylene or polypropylene, which are examples of thermoplastics, are added to bitumen, the characteristics of the bitumen are improved, and the result is a higher softening point and a lower degree of penetration. Additionally, this component raises the high temperature at which PG or performance grade bitumen can be used, which results in improved performance of bitumen in tropical regions. However, the findings of the study and the experiments have shown that the use of polyethylene leads in the bitumen being more brittle at lower temperatures. It is important to keep in mind that the use of polyethylene polymer in colder places not only does not result in an improvement in the qualities of bitumen, but it actually degrades the substance.
In general, depending on the kind of polymer, bitumen may take on a variety of characteristics, and here are a few of those characteristics that we will mention:
1- Raising the bitumen’s soft point, which prevents asphalt from being rutted during the summer and when temperatures are high.
2- Lessening the degree to which the bitumen penetrates the asphalt, which stops moisture from getting into the asphalt infrastructure when it rains.
3- Raising the elasticity or reversibility of bitumen, which raises the bitumen’s resistance against permanent deformations and, more crucially, lowers the number of fractures produced by the cold during the winter season.
In a stirred tank, a bitumen component is heated to a temperature between 185° C. and 221° C. and a block copolymer composition is added while the bitumen component is being stirred to form a homogeneous mixture. This method produces a PMB polymer modified bitumen binder composition in the substantial absence of cross-linking agents. A cured polymer modified bitumen binder composition is created by mixing the block copolymer composition with the homogeneous mixture and keeping the temperature between 185° C and 221° C for a length of time between 4 hours and 30 hours. Different types of polymers are utilized in this procedure, and they are selected based on a certain formula.
Polymer Modified Bitumen (PMB) specifications can vary depending on the intended use, such as roofing or paving, and the specific type of polymer used. However, there are some general characteristics and properties that are often specified:
Penetration: This is a measure of the hardness or softness of the bitumen, assessed by the depth a standard needle penetrates into a bitumen sample under specific conditions. PMB typically has a lower penetration value than unmodified bitumen, indicating a harder material.
Softening Point: The softening point is the temperature at which the bitumen becomes soft and less viscous. PMB generally has a higher softening point than unmodified bitumen, which means it can withstand higher temperatures before softening.
Elastic Recovery: This measures the bitumen’s ability to recover its original shape after being stretched or deformed. For PMB, the elastic recovery should be high, often above 70%, indicating a high level of flexibility and resilience.
Fatigue Resistance: PMB should exhibit excellent resistance to fatigue, meaning it can withstand repeated cycles of stress without failure.
Rutting Resistance: PMB is expected to have a high resistance to rutting, which is deformation or grooving that occurs over time, particularly in high-temperature conditions or under heavy loads.
Resistance to Aging: PMB should have a high resistance to aging, which means it can withstand exposure to the elements, including UV light and varying temperatures, without significant degradation over time.
Compatibility: PMB should be compatible with the aggregates used in road construction or the materials used in roofing applications.
Polymer Content: The amount and type of polymer used in the PMB must be specified. Common types include SBS (Styrene-Butadiene-Styrene) and APP (Atactic Polypropylene), and the polymer content is usually between 3-7%.
It’s important to note that specifications can vary by region and application, and different standards may apply. Examples of organizations that provide specifications for PMB include the American Association of State Highway and Transportation Officials (AASHTO), the Asphalt Institute, and the European Committee for Standardization (CEN). Always refer to local and application-specific guidelines when working with PMB.

The addition of polymers enhances the bitumen’s original qualities and introduces new characteristics, making it suitable for a variety of applications.
Enhanced Elasticity: PMB is more elastic than traditional bitumen, thanks to the inclusion of elastomeric polymers. This increased elasticity allows PMB to regain its original shape after being deformed, enhancing its resistance to rutting and fatigue cracking.
Improved Durability: PMB exhibits superior durability. The polymers help protect the bitumen from the effects of aging, oxidation, and UV radiation, leading to a longer lifespan and improved performance over time.
Greater Resistance to Temperature Extremes: PMB can withstand a broader range of temperatures without losing its structural integrity. It retains its flexibility in cold temperatures, reducing the risk of thermal cracking, and it is more resistant to softening and rutting in hot conditions.
Increased Adhesion: PMB’s adhesive properties are improved, ensuring better bonding with aggregate materials in road construction or with roofing materials, contributing to the overall durability of the finished structure.
Enhanced Resistance to Water Damage: PMB is more resistant to water damage than traditional bitumen. This quality makes it excellent for waterproofing applications and in environments where water damage could be a concern, such as roadways.
High Skid Resistance: PMB has high skid resistance, making it a safe option for high-traffic roadways and other areas where skid resistance is important for safety.
Superior Fatigue Resistance: PMB can handle repeated cycles of stress without failure, a crucial feature in applications like road construction where the material experiences constant loading and unloading from traffic.
These properties make PMB a preferred choice for applications demanding high-performance, longevity, and durability, such as road construction, roofing systems, and waterproofing projects.

Vehicle fleet expansion combined with improved road networks significantly raises tire wear rates, pushing Styrene Butadiene Rubber market demand for tire compounds. Replacement tires already contribute 60% of total tire consumption in India, and Bridgestone has responded by committing USD 85 million to expand local production capacity. Radial tire adoption multiplies SBR usage per unit, further escalating volumes. Replacement cycles remain less affected by economic slowdowns than OEM demand, providing downside protection during industry troughs. Emerging Asia and Latin America therefore deliver a reliable mid-term uplift to global sales.
Shift Toward Low-Rolling-Resistance Tires in EU & China
Regulations aimed at fleet fuel efficiency elevate demand for solution SBR grades that enable silica-filled tread compounds with lower hysteresis. EU consumer labeling has already shifted purchasing toward A-rated rolling-resistance products, with manufacturers recording 15-20% volume growth in these premium categories[1]European Commission, “Tire Labeling Regulation Impact Assessment,” ec.europa.eu. China mirrors the trend in heavy-duty segments, translating to sizeable opportunities for suppliers capable of advanced functionalisation. The widening performance gap between emulsion and solution SBR reinforces price premiums for high-spec polymers while rewarding R&D-driven producers.
Rapid Highway & Airport Construction Boosting Polymer-Modified Asphalt
Asia-Pacific infrastructure programs accelerate consumption of SBR-modified asphalt that delivers enhanced rutting resistance and flexibility. Laboratory data show 18.8% higher stability and 46.2% stronger dynamic creep stiffness when 5% SBR is blended into asphalt binders[2]Illinois Department of Transportation, “Polymer Modified Asphalt Performance Study,” idot.illinois.gov. Such performance gains justify the material premium for runways and expressways exposed to extreme loads. Because infrastructure spending is usually multi-year, the application gives producers a long-wave demand pillar that diversifies away from cyclical automotive sales and strengthens the Styrene Butadiene Rubber market.
OEM Push for 10% Tread Weight Reduction via Functionalised S-SBR
Automakers require lighter tires to improve fuel economy and extend electric vehicle range, stimulating uptake of functionalised S-SBR with stronger filler bonds. Michelin’s roadmap to produce bio-based synthetic rubber with 40% renewable content by underscores this objective. Weight-reduction programs favour suppliers that provide low-density yet durable tread polymers, creating premium margin pools. The resulting design complexity raises switching costs, deepening customer relationships for incumbents with advanced compounding know-how.

Feedstock costs typically represent up to 70% of total SBR manufacturing expenses, leaving margins exposed when crude prices spike. Currency swings add a further layer of unpredictability for exporters. While natural rubber rallies in temporarily improved SBR’s relative cost position, dual increases in crude derived butadiene quickly eroded that advantage. Long-term supplier contracts with fixed pricing clauses limit the industry’s ability to pass on sudden feedstock hikes, forcing many firms to adopt hedging and inventory strategies that raise working capital requirements.
Growing TPE Substitutes in Footwear
Footwear brands increasingly specify thermoplastic elastomers to streamline injection-molding processes and support recyclability commitments. TPE materials also simplify color matching and reduce cure times, compressing production cycles. Although SBR retains superior abrasion resistance for demanding athletic soles, casual and fashion segments migrate toward TPE at an accelerating pace. The shift pressures Styrene Butadiene Rubber industry volumes in a historically stable end-use segment, stimulating research into more sustainable SBR grades.
By Type: Solution SBR Drives Premium Applications
Solution SBR recorded the highest 4.34% CAGR through , even though emulsion SBR controlled 71.13% of volumes. The Styrene Butadiene Rubber market size attributed to solution grades is projected to expand from USD 4.08 billion in to USD 5.06 billion in , reflecting granular demand for high-performance tire treads. Functionalised solution polymers achieve tighter molecular weight distributions and superior filler compatibility, enabling tread weight reductions without compromising wet grip. ARLANXEO’s recent capacity addition in Dormagen aligns with automaker requirements for low-rolling-resistance tires. As performance specifications tighten, solution SBR gains share, particularly in Europe, China, and premium replacement markets where consumer awareness is highest. Emulsion SBR remains indispensable in mass-market segments thanks to scale advantages, extensive installed reactor base, and wide compounding latitude. Yet its price-driven positioning leaves margins vulnerable to feedstock swings. Blended distribution strategies that pair low-cost emulsion platforms with premium solution offerings thus protect revenue streams across automotive cycles.
The Styrene Butadiene Rubber market share commanded by solution grades is likely to rise by 3 percentage points by , supported by ongoing tire label regulation, electric vehicle proliferation, and OEM sustainability targets. Even in cost-sensitive emerging economies, policy-driven requirements for wet-grip and rolling-resistance performance accelerate migration to solution SBR. Producers investing in continuous processes, advanced catalyst systems, and in-line functionalisation can capture premium pricing while lowering variable costs via energy efficiency improvements and digitalised plant control.
By Application: Adhesives Emerge as Growth Driver
Tires contributed 69.38% of revenue, anchoring overall Styrene Butadiene Rubber market demand. The segment benefits from resilient replacement cycles, with commercial vehicle fleets valuing SBR’s abrasion resistance and cost-effectiveness. However, adhesives represent the most dynamic application, advancing at 4.52% CAGR toward . The Styrene Butadiene Rubber market size for adhesives is set to increase from USD 1.12 billion in to USD 1.39 billion by as construction outlays, e-commerce packaging volumes, and do-it-yourself consumer projects rise. SBR-based emulsions deliver strong adhesion on porous substrates like concrete and cardboard, combined with flexibility needed for temperature cycling. Packaging firms also adopt SBR hot-melt formulas that support mono-material recycling streams, helping them meet circular-economy pledges. Concurrently, high-growth Asian residential development fuels demand for tile adhesives, waterproof coatings, and sealants that require elastomer modification for crack bridging and impact resistance.
While footwear compound demand faces TPE substitution, premium athletic shoes still rely on SBR’s wear characteristics in high-abrasion outsole segments. Industrial goods including drive belts, hoses, and vibration isolators provide additional diversification, stabilising producer order books when automotive production fluctuates. These varied applications collectively reinforce the Styrene Butadiene Rubber market’s multi-sector resilience, though strategic focus is shifting toward higher-margin, differentiated formulations rather than pure volume pursuits.
Asia-Pacific maintained 45.64% revenue share in and is projected to grow at 4.28% CAGR through . China anchors regional dominance with extensive captive tire and synthetic rubber capacity, enabling fast scale-up for both emulsion and solution grades. Domestic demand receives a boost from rising car parc, infrastructure stimulus, and national recycling quotas that release capacity for export. India’s market is propelled by a forecast doubling of tire industry revenue to USD 22 billion by , spurring incremental capacities and backward integration investments. Thailand and Malaysia complement upstream supply via natural rubber output, affording compounders integrated sourcing advantages. However, carbon pricing, stricter air-emission norms, and water-pollution controls could trigger cost escalations or relocation of older SBR assets within the bloc.
North America delivers mature yet steady consumption underpinned by replacement tires, polymer-modified asphalt for highway rehabilitation, and adhesive uptake in e-commerce packaging. United States tire makers continue to emphasise performance niches such as light-truck and ultra-high-performance variants that lean heavily on functionalised solution SBR. Mexico’s emergence as a near-shoring hub for motor vehicle assembly adds incremental demand for automotive rubber parts. Canadian mining and oil sands operations keep industrial SBR uses buoyant, particularly in conveyor belts and protective coatings. Overall, regional growth hovers close to the global average but skews toward higher value polymers.
Europe is constrained by a lower vehicle production trajectory but benefits from the EU’s sustainability agenda that favours advanced and lower-carbon SBR. German, French, and Italian tire plants intensify adoption of eco-performance grades, amplifying imports of solution SBR from Korea and Singapore until European capacity expands. Eastern European highway and airport upgrades stimulate polymer-modified asphalt usage, partially offsetting automotive softness. The upcoming CBAM will likely curtail high-carbon imports and encourage local sourcing or renewable-energy upgrades in exporting countries. Scandinavian and Benelux markets lead on recycled SBR applications in flooring and sports surfaces, fostering niches that valorise circular solutions.
The Styrene Butadiene Rubber market is moderately concentrated, with the top five players accounting for an estimated 56% of global revenue. ARLANXEO, LANXESS, and JSR Corporation retain competitive advantage through process technology, diverse product portfolios, and integration with butadiene feedstock. ARLANXEO’s Dormagen line upgrade lifts annual solution SBR output by 70 kilotonnes, targeting premium EU tire customers. LANXESS leverages backward integration into anionic polymerisation catalysts, lowering variable costs. JSR expands capacity in Yokkaichi to service domestic automakers’ high-specification requests.
Chinese entrants such as Sinopec and TSRC are adding emulsion and solution reactors to supply fast-growing domestic consumption and pursue export share, intensifying price pressure in commodity grades. Western incumbents respond by pruning non-core assets, exemplified by Goodyear’s USD 650 million sale of its Beaumont synthetic rubber business to Gemspring Capital in . Partnerships around circularity are emerging as decisive. Sumitomo Rubber collaborates with Mitsubishi Chemical to recycle recovered carbon black into new tire compounds, reinforcing its cradle-to-cradle narrative. Michelin’s commitments to bio-based feedstocks and next-generation pyrolysis showcase how sustainability driven differentiation trumps pure capacity expansion in the long term.
