warm mix foamed XFP30 bitumen mix plant

  • 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.

  • Cold recycling - Foamed bitumen - WIRTGEN GmbH

    Cold recycling with foamed bitumen can be performed either in-situ (on site) or in-plant (in a mixing plant). When cold recycling in-situ, a cold recycler granulates the damaged road pavement while at the same time mixing in foamed bitumen, water and cement in the required quantities.

    There was found to be little difference between the performance of the warm and half-warm mixes against a section of road laid using hot-mix asphalt. Early results gathered from the study have pointed towards the conclusion that the same degree of compaction can be achieved in a foamed bitumen produced at 90°C as a hot mix produced at 150°C.
