Surface dressing is a thin surface treatment consisting of successive layers of bitumen emulsion and aggregates.
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
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
The curing layer is used to protect road layers made with, for example, hydraulically treated/ bound materials or Grave Emulsion mixtures
Grave Emulsion is used for small maintenance, reprofiling, reinforcement and in new road bases.

Semi rigid pavements
Associated techniques
Bonding of successive pavement layers safeguards the structural integrity of the entire pavement.
