A new $1km$ long road will be designed with traffic composition and design parameters as shown in Table $1$ and $2,$ respectively. The road should be designed with a service life between

$10$ to $15$ years. The road consists with three $(3)$ lanes in the design direction. General cost is shown in Table $3.$

Table $1$: Daily traffic compositions

Table $2$: Design parameters

Table $3$: General costs

With flexibility to assume any unprovided information and conservative design is to be used, you are required to design the most appropriate pavement structure complete with the

estimated cost.
