Facts & Figures

• In fact, Road Durability Improvement: PMB-enhanced asphalt increases road lifespan by 40-50% compared to conventional bitumen.
• Temperature Resistance: PMB can withstand temperatures ranging from -20°C to 70°C, making it ideal for extreme climates.
• Recycled Asphalt Usage: Some PMB formulations incorporate up to 30% reclaimed asphalt pavement (RAP), promoting sustainability

Key Developments:

• In January 2025, India's vast network of national highways continues to play a crucial role in the country's economic development and improved connectivity. The National Highways Authority of India (NHAI), responsible for developing, maintaining, and managing these highways, remains a key driver of this initiative. NHAI's efforts are especially significant in regions such as Uttar Pradesh and Bihar, where robust road infrastructure is essential for regional growth and prosperity.
• In August 2024, National Highways announced the extension of its trials on bio-binders to incorporate warm mix asphalt (WMA) and recycled content. This initiative aims to develop a lower-carbon, Clause 942 thin surface course solution, supporting the organization's efforts to achieve its net-zero objectives. Heidelberg Materials has supplied its Carbon Lock asphalt, which contains polymer-modified bitumen (PMB) bio-binders and is produced as both hot mix and warm mix asphalts. The material also includes up to 30% reclaimed asphalt to test the feasibility of various configurations.

Polymer Modified Bitumen Market segmentation

Based on the product:

• Elastomeric Polymers
• Plastomeric Polymers

The Elastomeric Polymers segment, particularly Styrene Butadiene Styrene (SBS), dominates the Polymer Modified Bitumen (PMB) Market due to its exceptional flexibility, durability, and resistance to deformation. SBS-modified bitumen is widely used in high-performance road construction, roofing, and waterproofing applications, making it the most preferred polymer modifier. The increasing demand for long-lasting road infrastructure in regions experiencing extreme climatic conditions further boosts its adoption. Additionally, SBS-enhanced PMB offers superior crack resistance and adhesion, reducing maintenance costs and improving road safety. As global infrastructure projects expand, the reliability and versatility of SBS continue to drive its market leadership.

Based on the Grade:

• PMB 40
• PMB 70
• PMB 120

Among the various grades, PMB 40 holds the largest share in the Polymer Modified Bitumen (PMB) Market, primarily due to its superior strength, durability, and resistance to heavy traffic loads. This grade is widely used in highway construction, airport runways, and bridge decks, where enhanced performance is crucial to withstand extreme stress and varying climatic conditions. Its excellent rutting resistance and long lifespan make it a preferred choice for high-traffic zones and heavy-duty pavements. With increasing investments in expressways and smart road projects, the demand for PMB 40 continues to rise, reinforcing its dominance in the market.

Based on the Application:

• Road Construction
• Bridge Construction
• Roofing Systems
• Railway Systems
• Others

Road construction leads the Polymer Modified Bitumen (PMB) Market, driven by the increasing demand for durable and high-performance road infrastructure. Governments worldwide are investing heavily in highway expansions, expressways, and urban road networks to support economic growth and improve transportation efficiency. PMB-enhanced asphalt offers superior resistance to rutting, cracking, and weather fluctuations, making it the preferred material for high-traffic roads and extreme climatic conditions. Projects such as India’s Bharatmala initiative and the U.S. Interstate Highway modernization are fueling demand for PMB in road construction. With a strong emphasis on sustainable and long-lasting pavements, this segment continues to lead the market.
