Question $3.$

Given the following data for a $7$day Traffic count for local roads in a moderate to dry climate with a granular base. Design life for the road is $20$ years. Vehicle growth rate is $\backslash (6\backslash \%\backslash ).$ Assume all vehicles are loaded. Calculate Average Daily traffic $($ADT$)$ and the ADT for each vehicle class, Average Annual Daily traffic $($AADT$),$ cumulate estimated standard Axles $($CESA$)$ and determine the traffic class loading in accordance with the $2019$ RDA pavement design manual for Low volume seal roads.

Question $3$a$.$ From the traffic data above draw a proposed cross section a pavement configuration from the design catalogue CHART G$1($source SATTC Pavement design manual$)$ on the next page indicating the required thicknesses of the various pavement layers, given that the existing subgrade has a CBR value of $\backslash (4\backslash \%\backslash ).$
