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.
