ABSTRACT:
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 R1, R2, R4and R5designate a hydrocarbon group of 6–22, preferably 8–20 carbon atoms, and the remaining R1, R2, R4and R5groups are an alkyl group with 1–4 carbon atoms, and/or a group —(A)2H, where A is an alkyleneoxy group with 2–3 carbon atoms, and s is a number from 1–4, R3is an alkylene group with 2–4 carbon atoms and n is a number from 0–2.
