The present invention relates to an aqueous quick-setting bitumen-aggregate mix suitable for cold pavement of roads, parking places, sidewalks and the like. The bitumen-aggregate mix is manufactured by mixing a mineral aggregate, water, a de-emulsifier, containing hydraulic cement, and a cationic oil-in-water bitumen emulsion, containing, as an emulsifier, a salt of a tertiary diamine and a phosphoric acid. The diamine has the formula (I), where one or two of the groups R.sub.1, R.sub.2, R.sub.4 and R.sub.5 designate a hydrocarbon group of 6-22, preferably 8-20 carbon atoms, and the remaining R.sub.1, R.sub.2, R.sub.4 and R.sub.5 groups are an alkyl group with 1-4 carbon atoms, and/or a group -(A).sub.2H, where A is an alkyleneoxy group with 2-3 carbon atoms, and s is a number from 1-4, R.sub.3 is an alkylene group with 2-4 carbon atoms and n is a number from 0-2.
