Question $3$

If the pavement shown in the figure below is a two$-$lane highway, design the welded fabric and

tie bars. Assume that the modulus of elasticity of concrete $=4\mathrm{.}6{10}^6,$ Poisson ratio of

concrete $=0\mathrm{.}15,$ unit weight of concrete $=150pcf,$ modulus of elasticity of steel is $29{10}^6,$

Poisson ratio of steel is $0\mathrm{.}25,$ and coefficient of friction between slab and subgrade is $1\mathrm{.}5.$

Assume allowable stress in steel in $27,000$ psi. $($Assume h$=11$ in$).$
