Laying a bituminous mix

The laying technique to be used is decided on the basis of the daily tonnage of mix to be laid:

  • on a motorway when two lanes are laid simultaneously, a single machine (a paver) is used, generally with a high rate continuous feeder
  • in the case of overlays, when the road is not closed to traffic a less powerful machine is generally used that operates on half the carriageway at a time
  • a paver with a telescopic screed is used for construction or maintenance works when the laying width is variable.

Laying involves spreading the mix in a layer of constant predetermined thickness and then compacting it.
