  • 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.

  • Laboratory Evaluation of Foamed Warm Mix Asphalt

    Many of New Jersey’s asphalt suppliers have elected to invest in Warm Mixed Asphalt systems that utilize water to foam the asphalt. Foaming the asphalt binder reduces the viscosity of the asphalt binder by increasing its surface area. Theoretically, this provides a more uniform coating on the aggregates, as well increasing the workability

  • Warm Mix Systems - Astec Inc.

    The benefits of warm mix asphalt, such as reduced energy consumption, lowered emissions, and elimination of visible smoke, are well-known in the asphalt paving industry. Warm mix technology allows mix to be prepared and placed at lower temperatures than conventional hot mix. To achieve this, the viscosity of the liquid asphalt cement (AC) must remain low at the reduced temperatures.
