Cold mix application including slurry seals and microsurfacing
This has the following effects :
- Risk of aquaplaning, loss of driving control
- Water penetration into surfaces though cracks associated with rutting
- Levelling and rut filling of surface
- if necessary, strengthen the pavement structure if it is no longer in line with the volume of traffic.
The techniques used depend on the magnitude of the rutting or location of structural deformation.
In the case of structural deformation :
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.
