ButaPhalt and Asphalt Crosslinkers for Modern Bitumen Additive Strategies

For decades, the performance of polymer modified bitumen (PMB) has relied heavily on the ability of polymers to integrate effectively within the bituminous phase. While early systems delivered meaningful improvements in rutting resistance and elasticity, they also introduced persistent production and storage challenges such as phase separation, inconsistent dispersion, and processing instability. To address these issues, the industry turned to [...]

Improving PMB Performance with PGXpand Polymer Modifier

Polymer modification is an essential part of modern asphalt pavement design. As road networks are subjected to heavier traffic volumes, higher axle loads, and increasingly demanding environmental conditions, conventional binders can struggle to provide the durability required for longer service lives. To address these challenges, the asphalt industry has increasingly turned to polymer modified bitumen (PMB) systems to improve pavement performance. Today, polymer modified asphalt is widely used on highways, intersections, and other [...]

Sustainable Bitumen Additives to Extend Asphalt Lifespan

Sustainability may be one of the defining priorities in pavement and roofing construction. Governments, producers, contractors, and asset owners are all under pressure to reduce emissions, conserve resources, and improve the long-term environmental performance of infrastructure. However, one misconception still persists throughout the industry: that sustainable solutions require sacrificing cost, durability, or long-term performance. Advances in asphalt chemistry are proving the opposite. Sustainable bitumen additives are helping producers create [...]
