摘要

ABSTRACT OF THE INVENTIONAn improved mixing process for aqueous bituminousemulsion-aggregate slurries is disclosed whereby cationicemulsions are prepared by emulsifying bitumen, such as anasphalt, in water with a new kind of cation-activeemulsifier which is the product of the reaction of apolyamine with certain polycarboxylic acids wherein one ormore additives selected from the group consisting of apolyamine, ammonia, magnesium sulfate, cupric sulfate,chromium chloride, ferric sulfate or dilute sulfuric acidis added to the mixing water to extend the mixing time andto give mixes with good flowability and flotationcharacteristics.
