Improving the performance of polymer-modified asphalt (PMA) while making production more efficient and safer is an important challenge for the asphalt industry. Research into advanced crosslinking technologies offers promising opportunities to address these priorities together. At the 2026 AMAP Annual Conference & Workshop, researchers from the University of Oklahoma and the University of Wisconsin presented research exploring these [...]
Successful delivery of the products that keep businesses and services moving depends on the people who get behind the wheel. By reliably transporting materials across hundreds, if not thousands, of miles, professional drivers form an essential link in the supply chain. At Sripath, our products support customers across the world, helping them improve the production and performance of asphalt and [...]
Roofing materials must balance durability, flexibility, adhesion, and processability to perform reliably across changing temperatures and weather conditions. Bitumen remains a key component in roofing products because of its waterproofing properties and versatility. However, the characteristics of the base bitumen and the frequently varying quality of incoming bitumen can make formulation and processing challenging. Asphalt additives known as bitumen softeners can help formulators address some of these challenges. Softeners can make it easier to [...]
For many polymer modified bitumen (PMB) producers, equipment fouling is an unavoidable cost of doing business. Build-up on mixers, transfer lines, storage tanks, and production equipment increases downtime, creates maintenance issues, and reduces production efficiency. While traditional sulfur crosslinking remains an effective way to improve binder performance, the crosslinking process itself can contribute to difficult cleanups that cost producers time and money. Asphalt producers need more than a [...]
