Foamed Bitumen | Croda Industrial Chemicals

Foamed bitumen is made via a procedure in which cold water (2 - 3%) is injected into hot bitumen (~180°C), which causes spontaneous foam formation. Upon contact with the hot bitumen the water is turned to vapour and trapped in thousands of small bitumen bubbles, thus temporarily altering the physical properties of the bitumen.
