    Abstract: A bituminous cold-mix for road building and similar paving uses is made by a process comprising the steps of: (a) applying to an aggregate of mixed particle size a first bitumen emulsion of relatively high breaking index (e.g., 190 or more, NFT 66.017) to coat at least 80 % of the aggregate surface with no more than 5 weight % (e.g. about 2 weight %) of residual bitumen; and (b) applying to the coated aggregate from step (a) a second bitumen emulsion having a breaking point no higher (e.g., 190 or less) than that of the first emulsion to produce fully coated aggregate particles. The invention also includes roadways and similar paved areas constructed using the cold- mix.

    Abstract: A bitumen emulsion having a viscosity of at least 200 cSt at 25 °C which comprises bitumen, an emulsifying agent, an inorganic acid, water and from 0.1 to 3.0 wt% of a metal salt, the metal being selected from lithium, sodium, potassium, magnesium, calcium and aluminium. Preferably, the metal salt is a chloride, for example calcium chloride. The emulsion is produced using a static mixing process.
