An evaporation-filtration test has been developed which attempts to characterize asphalt emulsions by inversion point. At usual asphalt contents, emulsions are of the oil-in-water type. After spraying, the water evaporates from the emulsion and the asphalt content increases, leading to coalescence, which would be expressed in terms of inversion to the water-in-oil type. The point at which this inversion occurs depends on many parameters. An investigation of some of these parameters is proposed.
