摘要

Liquid bitumen at a temperature of 120 - 160oC is mixed with 1-3% by weight of water in a mixing device (8) at a pressure which is higher than the saturation pressure of water vapor at the temperature of the hot bitumen. From the mixing device the mixture is allowed to expand through a valve (10) such as a throttle valve, the resulting evaporation of the water in the mixture causing the desired foaming of the bitumen.
