For the construction of a highway, a cut is to be made as shown in the figure. The soil exhibits $c'=20$ kPa, $\phi'=18^{\circ}$, and the undrained shear strength $=80$ kPa. The unit weight of water is $9.81 kN/m^3$. The unit weights of the soil above and below the ground water ... conditions, respectively, would be $1.6$ and $0.9$ $0.9$ and $1.6$ $0.6$ and $1.2$ $1.2$ and $0.6$

A two lane, one-way road with radius of $50$ m is predominantly carrying lorries with wheelbase of $5$ m. The speed of lorries is restricted to be between $60$ kmph and $80$ kmph. The mechanical widening and psychological widening required at $60$ kmph are designated as $w_{me,60}$ and $w_{ps,60}$, ... $1.19 \:m, 0.50 \:m, 0.89 \:m, \text{ and } 0.50 \:m$

A super-elevation $e$ is provided on a circular horizontal curve such that a vehicle can be stopped on the curve without sliding. Assuming a design speed $v$ and maximum coefficient of side friction $f_{max}$, which one of the following criteria should be satisfied? $e \leq f_{max}$ $e > f_{max}$ no limit on $e$ can be set $e = \dfrac{1-(f_{max})^2}{f_{max}}$
