They are intended for the routine maintenance of pavements (localized repair, patch work, trench filling, pothole repair or re-instatements etc.) or for small works; they do not play a structural role.
Once applied on site, properties evolve, as a result of the evaporation of volatile fractions and/orevacuation of the water: these phenomena are accompanied by a compaction of the asphalt mix with an increase of its mechanical resistance.
Given higher initial void contents of these emulsion based mixes, binder – aggregate adhesion must be specially considered.
For specific cases, like filling potholes and localized repairs, the “projected” cold asphalt mixes technique can be applied.
