  • Foamed Warm Mix Asphalt Design Issues

    The majority of contractors implementing Warm Mix Asphalt (WMA) in Arkansas have elected to use plant‐foaming units. However, laboratory mix designs are prepared without foaming. A laboratory‐ scale foaming device may be necessary for agency verifications of WMA mix designs. In this study,

  • Warm Mix Asphalt – What is it and how can we benefit?

    – Blended with the dry aggregate – Releases water at elevated temps over time – Creates a controlled foaming effect which lasts until the temperature drops below 212° F (100°C) • When the water turns to steam – It expands by a factor of 1,673 – Expands & cools the asphalt – Reduces the viscosity.

  • 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.

    Differences between Warm Mix and Hot Mix Asphalt. Warm mix asphalt is produced using temperatures 30 to 120 degrees Fahrenheit lower than what is used for traditional hot mix asphalt. Less energy is needed to heat the warm mix asphalt, so it uses less fuel, decreasing the plant's carbon footprint.
