Abstract

The invention relates to an additive for a bitumen emulsion, which is a specific mixture of alkoxyiated compounds with low and high amounts of alkylene oxide units, in combination with a polyaluminum compound. Using this additive it is possible to prepare an aqueous slow-setting bitumen emulsion-aggregate mix suitable for cold paving of roads, parking places, sidewalks, and the like.
