A two lane highway with two $3\mathrm{.}7m$ lanes, has a design speed of $120k\frac{m}{h},$ has maximum

allowable coefficient of side friction, the roadway is moving down and turning to the

right.

Calculate chainages, superelevation rates and levels on the left hand side $($LHS$),$

centerline $($CL$)$ and right hand side $($RHS$)$ of the road starting from end of normal camber

$($NC$)$ at $CH1675\mathrm{.}897m.$

Determine the above required information only at the following points, normal camber

$($NC$),$ level and normal camber $($LNC$),$ Normal Cross$-$fall $($NCF$),$ beginning of horizontal

curve $($BHC$)$ and at full superelevation $($full$-$e$)(35$ marks$)$

Information:

Curve radius

$=$ Minimum radii of horizontal curve $(530$m$)$

Camber

$=2\%$

Chainage @ BHC

$=1737\mathrm{.}832m$
