Question

The data given below pertains to the design of a flexible pavement:
Initial traffic = 1250 cvpd
Design life = 10 years
Traffic growth rate = 8% per annum
Vehicle damage factor = 3
Iane distribution factor = 0.5
The design traffic in terms of million standard axle to be catered would be

Answer 1

The cumulative number of standard axle load,
$N_S=\frac{365A\left[\right(1+r{)}^n-1]}{r}\times VDF\times F$
$\Rightarrow N_S=\frac{365\times 1250\times 0.5\times \times 3[{(1+\frac{8}{100})}^{10}-1]}{\frac{8}{100}}$
$=9.91msa$
