Warm Mix Asphalt (WMA) technology refers to a group of technologies that allow asphalt mixtures to be produced and placed at lower temperatures than traditional Hot Mix Asphalt (HMA). This reduction in temperature affects both construction and performance. During construction, WMA offers several advantages. Reduced emissions are a key benefit. Lower mixing and compaction temperatures result in reduced emissions of volatile organic compounds (VOCs) and greenhouse gases. Improved workability results from the lower temperatures make the mix easier to compact, especially in cooler weather or for long haul distances. Extended paving season is another advantage,....
