Question $6$

A continuous reinforced concrete pavement using limestone as coarse aggregate is subjected to $5{10}^6$ESAL. Assume $k=75$pci,$E_c=4{10}^6,MR=650,Cd=1\mathrm{.}05,J=2\mathrm{.}9,R=95\%,So=0\mathrm{.}3,\frac{}{P}SI=2\mathrm{.}0,DT{T}_D=60F,$ and wheel load due to construction traffic $=14,000lb.$ Determine the thickness of the concrete pavement and the number of No$.5$ bars per $12$ ft $.$ lane required.
