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.
Sripath Resource Series: Warm Mix Asphalt
Conversations are picking up across the asphalt paving industry regarding technologies to improve environmental outcomes without affecting roadway performance. Warm mix asphalt (WMA) continues to take the lead in these discussions as mix designers and engineers explore how lowering production and compaction temperatures impacts performance outcomes on job sites.   Warm mix additives are materials added to asphalt mixtures [...]
