Warm Mix Asphalt - EAPA
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). The information on this website focuses on Warm Mix Asphalt (WMA) technologies for producing asphalt at temperatures slightly above 100 °C with properties or performance equivalent to that of conventional HMA.

A Warm Mix Agg-Net
Asphalt described as warm mix is typically heated to between 100°C and 140°C, around 40°C less than hot-mix asphalt. Nynas also offer a ‘half-warm’ mix whereby asphalt is produced at between 70°C and 100°C. Lowering the mixing temperature of asphalt not only reduces the energy needed to heat raw materials during production, but also generates fewer emissions.
