Which bitumen emulsion grades are technically suitable for tack coat in asphalt paving?

[Jasper]

Tack coat typically uses cationic rapid or controlled setting emulsions designed to form a thin, uniform bond between asphalt layers. The chosen grade must break reliably on the existing surface, cure within the paving schedule, and provide strong interlayer adhesion. In practice, selection depends on ambient temperature, surface condition, and the local specification. Modified emulsions may be used where higher bond strength, moisture resistance, or heavy traffic demands justify additional cost.
