Warm Mix Asphalt


Warm mix asphalt (WMA) is the latest trend in asphalt technology - the materials and production of WMA is the same as hot mix asphalt, only it is produced at cooler temperatures with the help of additives (whether chemical, wax, or water).  The additives help to reduce binder viscosity at lower temperatures for better aggregate coating.  There are numerous benefits of WMA, including:

  • Lower fuel and energy usage at the plant
  • Fewer emissions at the plant and paving site
  • Increased worker comfort
  • Better workability
  • Compaction aid
  • Longer haul distances
  • Longer paving season
