Warm Mix Asphalt - EAPA

Hot Mix Asphalt is produced and mixed at temperatures roughly between 120 and 190 °C The production temperatures of Hot Mix Asphalt depend on the bitumen used. The lower mixing and paving temperatures, obtained by the use of Warm Mix Asphalt, minimise fume and odour emissions and creates cooler working conditions for the asphalt workers.

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 ...
