Q$2)(70$ pts$)$ the plan and the cross$-$section of a two lane highway segment are shown below. O$.$E$.$ I.E$.$

$R=350mB(Km$:$2+680)$

The road rises at a uniform grade of $2\%$ from A to B$.$ The design speed $(Vd)$ is $90k\frac{m}{h}.$ The radius $(R)$ of the circular curve is $350$ m $.$

a$)$ Prepare superelevation table showing superelevations of each travel lane and the elevations of $CL,OE,IE$ at $10$ m even stations starting from the beginning of Lt Distance up to the ending point of Ls distance.

b$)$ Draw superelevation diagram showing all necessary details. Notes:

Use emax $=0\mathrm{.}1(10\mathrm{.}0\%)$

Use AASHTO Method $5$ for superelevation

Apply Superelevation by rotating around CL$.$

For locating superelevation runoff $($Ls$),$ apply Turkish practice:

Add critical stations $($End TR$/$Start LS$,$ PC$)$ in superelevation table.
