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 [...]

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 [...]

Choosing the Right Asphalt Softener: What Producers Should Know

Asphalt mix design requires more than simply selecting aggregates and binder grades. Producers are expected to balance performance, durability, sustainability, workability, and cost efficiency all at once. As asphalt formulations become increasingly sophisticated, the role of asphalt modifiers and asphalt additives has expanded significantly, especially when it comes to managing asphalt viscosity and improving binder performance. Among the most important tools [...]
