The latest Life Cycle Assessment on polymer modified for bitumen is now available
Eurobitume has just published a new Life Cycle Assessment (LCA) examining the environmental impacts associated with the production of polymer modified bitumen (PMB) in Europe.
Widely used in road construction, polymer-modified bitumen is designed to improve pavement performance, particularly under heavy traffic and varying temperatures. By enhancing durability and resistance to deformation, PMB can contribute to longer-lasting road infrastructure.
The study presents a cradle-to-gate life-cycle impact assessment of SBS-based PMB produced in refineries representing Eurobitume members across Europe. The assessment aims to provide robust environmental data to support future product evaluations and enable more consistent environmental comparisons based on a specified functional unit.
The study focuses specifically on SBS-based PMB formulations, which account for a significant share of current paving applications. Other polymer types are not included, and therefore, the results should not be considered representative of all PMB formulations.
The Life Cycle Assessment evaluates two representative paving products: a standard PMB containing 3.5% SBS and a high-performance PMB containing 6% SBS. The results are presented in compliance with EN 15804 and include Global Warming Potential indicators.
Ahead of the study’s publication, Eurobitume organised a webinar on 29 April 2026 to present the key findings and discuss the role of PMB in sustainable road infrastructure. The webinar recording is now available on the Eurobitume website here.
