There is provided a dispersing emulsion excellent in storage stability and mechanical stability, particularly an asphalt modifier of an water based dispersing emulsion, which can be mixed with a hot asphalt or an asphalt emulsion, and can improve rutting resistance, toughness, and flexibility at a low temperature without losing workability. There is provided a dispersing emulsion of a thermoplastic elastomer, which is emulsified and dispersed in the presence of at least one nonionic emulsifier selected from the group consisting of a styrenated phenol poly(alkylene oxide), a poly(alkylene polyamine) poly(alkylene oxide), polyalcohol fatty acid esters, polyalcohol fatty acid esters poly(alkylene oxide), and a benzylated phenol poly(alkylene oxide).
