Abstract
An open-graded emulsified asphalt paving mix is provided comprising a major portion of open-graded aggregate and a minor portion of cationic or anionic bituminous emulsion, the mix containing a minor portion of a polyelectrolyte having the opposite electric charge from that of the asphalt emulsifier which imparts excellent water resistance properties to pavement prepared from the mix. A method for producing the polyelectrolyte in situ is also provided.
