The BASF evaluation explored the performance of the B2Last® + SBS (styrene-butadiene-styrene) modified asphalt binder. This advanced binder is designed to enhance durability, flexibility, and sustainability in pavement applications. The study was driven by the increasing demand for longer-lasting pavements and reduced maintenance cycles, which aligns with broader efforts to create sustainable infrastructure. B2Last® represents a leap forward in material innovation, offering a unique combination of properties aimed at addressing common pavement challenges, such as cracking and rutting, while reducing environmental impact.

The primary goal of this evaluation was to determine the performance capabilities of B2Last® + SBS modified asphalt under real-world conditions. The study incorporated both laboratory testing and field performance monitoring. Another key focus was the identification and investigation of any premature failures, particularly cracking, to refine application and construction practices. The scope of the project encompassed rigorous analysis of mechanical properties, field durability, and construction methodologies to ensure comprehensive insights into the binder’s performance.
