Asphalt Foaming Machine

Hot asphalt (eg, 150 ~ 160 ℃) encountered a very small amount of cold water (2 ~ 3%) will occur after the intense heat exchange so that the instantaneous vaporization of cold water, resulting in asphalt, “foam” phenomenon, the general “foam” of the asphalt known as foam asphalt. Asphalt in the “foam” in the process of rapid volume expansion for the original dozens or even dozens of times, the viscosity is greatly reduced, conducive to mixing and aggregates, so the foam asphalt is very suitable for road projects in the field of cold regeneration technology and warm mixing technology.
