Total amount of driving lanes Fr
With more driving lanes available on the road the trucks shall spread over the different lanes. When there are more lanes in one driving direction then the trucks will use mainly the right hand lane with partial use of the other lanes. In table 3.5 the correction factors are given based on experiences in The Netherlands.

One lane
Special lane 1,00 No overtaking
Two lanes 0,95 Three lanes or more 0,90

Truck damage factor Dv
To estimate the truck damage factor it is necessary to determine the kind of truck traffic on the road. There are 3 possible categories. In table 3.6 the relevant truck damage factors are given. This damage factors are used for viscous-elastic materials such as asphalt and RoadCem.
