Bitumen emulsions in road construction safeguard pavement durability thanks to their bond-, cure- and protection properties. Examples of pavement structures below provide an overview of the use of bitumen emulsions:

Low volume road/pavement

Associated techniques: Surface Dressings

Surface Dressings

Surface dressing is a thin surface treatment consisting of successive layers of bitumen emulsion and aggregates.

Impregnation

Impregnation consists of introducing a bituminous binder into a previously compacted but untreated road surface. The binder is allowed to penetrate into the pavement surface to stabilize fines and turn the upper part into a hydrophobic layer several millimeters thick.

Flexible Pavement

Associated techniques

Cure and Seal

The curing layer is used to protect road layers made with, for example, hydraulically treated/ bound materials or Grave Emulsion mixtures

Grave Emulsion

Grave Emulsion is used for small maintenance, reprofiling, reinforcement and in new road bases.

Impregnation

Impregnation consists of introducing a bituminous binder into a previously compacted but untreated road surface. The binder is allowed to penetrate into the pavement surface to stabilize fines and turn the upper part into a hydrophobic layer several millimeters thick.

Semi rigid pavements

Associated techniques

Tack-coats

Bonding of successive pavement layers safeguards the structural integrity of the entire pavement.
