Highway Pavement Design ,19, Design Traffic,

N (Design)=365[(1+r)^n-1]/r xAxDxF
Where N(design)= Cumulative no of standard axle to be carried on Road during Design Life.
D=Lane Distribution Factor
F=Vehicle Damage Factor
A= Initial Traffic ( commercial Vehicle per day) upon completion of construction
r=Annual Traffic Growth
Lane Configurations
The basis of a design traffic loading is passed over a single section of pavement (i.e. a single lane), where multiple lanes are used, consideration is often given to proportioning the traffic.
The magnitude in which this proportioning is undertaken is very much dependent on the nature of the section and the travel paths of the vehicles. It is, however, a common practice to adopt a reduced loading in the fast lane, particularly in a rural environment.
Heavy Vehicle Axle Configurations
The axle configuration of a heavy vehicle can affect the way in which the wheel loading is induced and how the pavement structure will perform.
The number of axles, location of the load and the payload can influence the design traffic loading and the number of ESAs/heavy vehicle.
