Organized by the Deutscher Asphaltverband (DAV) and the Deutsches Asphaltinstitut (DAI), this annual seminar marks a key moment for industry members to convene and explore the evolving technical and regulatory landscape of asphalt construction and materials. As the 40th anniversary edition of the Asphalt Seminar, the 2026 program reflects [...]

What Asphalt Crosslinking Actually Does and How ButaPhalt Is Different

Polymer modified bitumen (PMB) is a cornerstone of asphalt mix design, enabling pavements that can resist rutting, cracking, and aging under increasingly demanding traffic and climate conditions. While polymers provide the backbone of these performance improvements, the real durability of PMB depends on how effectively those polymers interact with the base bitumen. That interaction is where crosslinking plays a critical role. Crosslinking is often [...]

PGXpand®: The Road to Better Bitumen Performance

Innovation is often the result of years of asking the right questions, testing assumptions, and refining ideas until chemistry and application finally align. As Sripath Technologies celebrates 20 years of innovation, PGXpand® stands as a clear example of this philosophy in action. PGXpand was not developed to simply replicate what existing polymers already did for bitumen. Instead, its development began with a more fundamental challenge: [...]

Sripath Asphalt Additives and Proven Durability in Roadway and Roofing Applications

In modern asphalt mix design, the use of high-quality asphalt additives has become essential to improve performance, sustainability, and long-term durability. Whether the goal is to incorporate higher amounts of Reclaimed Asphalt Pavement (RAP), reduce production and compaction temperatures, or optimize polymer-modified bitumen (PMB) blends, additives can help producers achieve these objectives without compromising pavement life. Sripath has developed a suite of innovative additives including ReLIXER®, PGXpand®, [...]
