Test L: Fill in the blank for the following: Module reference Z When designing independent vertical and horizontal profiles on divided facilities, considerations should be given to the these profiles may have on future widening into the median. 2. When a motorist drives through a curve, the roadway is often tilted or banked at an angle, making it easier to the curve at a safe speed without skidding or tipping. distribution of load on wheels 3. Super elevation provides and hence uniform stress is offered on the foundation which results into less on wheel tires and springs as well as economy in maintenance cost of the road. 4. True or False: The design speed of both vertical and horizontal alignment should be compatible with longer vertical curves and flatter horizontal curves than dictated by maximum values. Test il Compute the following a) A highway intersect a grade of -1.6 % to a + 2.40 %, this curve provides a 140 m stopping sight distance for a design velocity of 31.11 m/s. Sketch and i.) Calculate the minimum length of the vertical curve (m) ? ii.) Find the location of the lowest point of the curve from PT (m)?
