Asphalt Additives for Roofing Compounds

For professionals formulating roofing compounds, creating a high-performing, durable, and cost-effective product is a constant challenge. Roofing systems demand materials that can withstand extreme temperatures and resist weathering and water damage. Bitumen membranes, a cornerstone of these systems, rely heavily on asphalt additives to meet these rigorous requirements. Among the most versatile tools available to formulators are PGXpand®, a bitumen friendly polymeric additive designed to optimize performance and enhance [...]

How Asphalt Crosslinking Impacts Long-Term Fatigue and Cracking Resistance

Asphalt pavements are subjected to a complex combination of mechanical stresses, environmental conditions, and temperature fluctuations throughout their service life. Fatigue cracking and surface deterioration are common challenges that can significantly reduce pavement lifespan and increase maintenance costs. One of the most effective strategies to combat these issues is PMB asphalt crosslinking, a process that enhances binder elasticity, cohesion, and resistance to micro-crack [...]

PGXpand® and Asphalt Performance in Extreme Climates

As infrastructure owners and contractors face increasingly volatile weather patterns, the demand for a climate-resilient asphalt binder has never been greater. From freeze-thaw cycles in northern regions to sustained high temperatures in the south and southwest, asphalt pavements are under constant stress. Performance is no longer defined solely by average conditions but rather a consideration of performance at extremes. Polymer modified bitumen (PMB) has long been [...]
