Warm Asphalt Mix (WAM)


Warm Mix Asphalt is an asphalt that is produced and applied at a temperature around 20 – 40 °C lower than an equivalent “Hot Mix Asphalt” (HMA).Asphalt workers benefits: less emissions and improved working conditions

It is a proven a technology that can:

  • Reduce paving costs.
  • Extend the paving season.
  • Improve asphalt compaction.
  • Allow asphalt mix to be hauled longer distances.
  • Improve working conditions by reducing exposure to fuel emissions, fumes, and odors
    • Environmental benefits: less energy used and lower emissions

    • Manufacturing and paving benefits: less hardening of the bitumen and full compatibility with the use of RAP
