Abstract
En bitumen emulsjon med en viskositet på minst 200 cSt ved 25°C omfatter bitumen, et emulgerings-middel, en uorganisk syre, vann og 0,1-3,0 vekt-prosent av et metallsalt, idet metallet er valgt fra litium, natrium, kalium, magnesium, kalsium og aluminium. Fortrinnsvis er metallsaltet et klorid, eksempelvis kalsiumklorid. Emulsjonen fremstilles under anvendelse av en statisk blandeprosess.A bitumen emulsion having a viscosity of at least 200 cSt at 25 ° C comprises bitumen, an emulsifier, an inorganic acid, water and 0.1-3.0% by weight of a metal salt, the metal being selected from lithium, sodium , potassium, magnesium, calcium and aluminum. Preferably the metal salt is a chloride, for example calcium chloride. The emulsion is prepared using a static mixing process.
