PMB mixes have been popular for decades and are designed to maintain the integrity of the roadway while enhancing functional performance characteristics. Most virgin bitumen lacks the complete properties needed in quality to build high-performing roadways. Adding polymers to create a PMB can help strengthen and toughen the roadway surface. PGXpand®, a bitumen-friendly polymer additive, is uniquely designed to allow polymer modified bitumen (PMB) producers to boost the high temperature performance of the binder while maintaining low temperature properties. It minimizes SBS content, improves viscosity, supports higher filler loading, and provides better stability.
Cost Savings and Lifecycle Value in the Asphalt Industry
Asphalt production and paving operations are under constant pressure to balance performance, efficiency, and cost. Agencies, producers, and contractors are expected to deliver durable pavements while managing fluctuating raw material prices, energy expenses, maintenance demands, and increasingly complex mix designs. As a result, the use of asphalt additives and asphalt modifiers has become an important strategy for optimizing production costs and long-term pavement value. Advanced additive [...]
