The present invention provides an asphalt emulsifying and dispersing agent from which an asphalt emulsion composition excellent in cement mixing property, aggregate mixing property, durability and storage stability of an asphalt emulsion can be obtained. A specific monomer 1, such as an ethylenically unsaturated carboxylic acid derivative having a polyoxyalkylene group, a phosphoric monoester monomer 2, and a phosphoric diester monomer 3 are copolymerized. An asphalt emulsifying dispersant containing the resulting polymer. [Selection figure] None |
