Warm mix asphalt is paving mix that can be produced and compacted at lower temperatures than traditional hot mix asphalt materials for roadway development. This may result in reduced greenhouse gas (GHG) and asphalt emissions through lower operational temperature requirements at the plant and at the job site. PHALANX®, a specially engineered warm mix additive, is designed to improve compactability of hot asphalt mixes and Polymer Modified Bitumen (PMB) mixes. It helps reduce the paving temperature when laying down a roadway. PHALANX helps lower the carbon footprint, reduce energy consumption, and deliver overall cost savings.
How Water Affects Asphalt Sustainability and Durability: From Pavement Performance to Energy Use
Water is one of the most persistent and underestimated forces acting on asphalt roadways. While traffic, climate, and materials all influence pavement performance, moisture often determines how long a surface lasts and how sustainable it truly is. Factors such as how water interacts with asphalt binder and aggregate and the hidden energy costs of removing moisture from aggregate or reclaimed asphalt pavement (RAP) piles are just the start of how water [...]
