emulsified cationic asphalt - emulsified asphalt in which the asphalt globules are electro-positively charged. Common grades of cationic emulsified asphalt are: CRS asphalt - cationic rapid-setting emulsified asphalt; CMS asphalt - cationic medium-setting emulsified asphalt; CSS asphalt - cationic slow-setting emulsified asphalt. Emulsified cationic asphalt is superior to emulsified anionic asphalt in its ability to mix with wet stones, or aggregate, because its electro-positive charge aids in rapidly replacing the water adhering to the stones.
