Foamed asphalt or foaming technology were originally used in asphalt stabilization in Iowa by Professor Csany in the 1950s. When hot asphalt meets water, the volume of asphalt is extensively increased by the water steam, creating a bubbled “foam” and resulting in reduced viscosity of asphalt but an improved workability and coatability of mixes.

TRANSPORTATION RESEARCH CIRCULAR

HMA is a composite material consisting of aggregate particles (hard pieces of rock) of different sizes, an asphalt binder that is much softer than the aggregate, and air voids. The response of HMA to traffic and environmental loads depends on the properties of the constituents and the proportion (by volume) of each.
