A pavement deforms under the effect of cumulative traffic loads (rutting,…). Rutting disturb pavement crossfall and prevents rain water to drain run off the surface. This results in longitudal channels (ruts) where water can build up.

This has the following effects :

  • Risk of aquaplaning, loss of driving control
  • Water penetration into surfaces though cracks associated with rutting

Actions

  • Levelling and rut filling of surface
  • if necessary, strengthen the pavement structure if it is no longer in line with the volume of traffic.

Techniques

The techniques used depend on the magnitude of the rutting or location of structural deformation.

Micro Surfacing

Cold mix application including slurry seals and microsurfacing

Grave Emulsion

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

Asphalt concrete with bitumen emulsions

Asphalt concrete with bitumen emulsion for wearing courses

 
In the case of structural deformation :

Grave Emulsion

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

Recycling with bitumen emulsions

Recycling with bitumen emulsions, in for example an asphalt plant or a Grave Emulsion type plant, consists of treatingmilled and screened asphalt planingsmaterials obtained from the demolition ofold pavement layers.
