Problem $1$NOMOGRAPH SOLNES:

a$)$ Given:

$-$HMA over over granular base over granular subbase over subgrade

$-$Water removing times are $1$ day for granular base and $2$ hours for granular subbase, saturation time is $20\%$ for all the layers.

Mr $($surface$)=400,000$ psi, CBR of granular base is $70$ and CBR of granular subbase is $40$ and

Mr of subgrade: Jan$-$Dec $(22,22,5\mathrm{.}5,5,5,8,8,8,8\mathrm{.}5,8\mathrm{.}5,6,22$ X$1000$ psi$)($Find average Mr as shown in the class using damage$)$

$*$ESAL is $3$ millions in design lane in design life.

$-$Reliability level, $R=85\%$

Standard deviation, $S=0\mathrm{.}45$

$*$Initial and terminal serviceability indices, $=4\mathrm{.}2,2\mathrm{.}5$

$-$Design the thicknesses of the layers. Sketch the thicknesses and mark the layers

Must add Figures that indicate the values obtained from them. $($SEE POSTED CLASS LECTURE FOR FIGURES$)$
