A new method is provided for emulsifing a asphaltrubber pavement repair material into a stable thixotropic emulsion capable of flowing as a liquid upon gentle agitation. The method generally comprises the steps of heating asphalt and rubber to form a jellied reaction product, and admixing a asphalt-rubber soap consisting essentially of water, an anionic water soluble emulsifying agent, a thickner, and the halide of an alkali metal or an alkaline earth metal to form a thixotropic emulsion capable of flowing as a liquid upon gentle agitation.
