The road alignment for the construction of a highway passes through a mountainous area. There is therefore the need to cut through the mountain for safe design of the road. You have been contracted to embark on a slope stability analysis for safe and economical design of the slope. Outline the procedure you will go through to achieve this purpose. 2. Explain why most slope failures do occur during the raining season, especially after heavy rain.

Civil Analysis of highway section A portion of a four-lane multilane highway with a full median carries 2,600 vehicles per hour during peak hours in the busiest direction. In the traffic flow, there are 2% RVs and 14% trucks. The facility's regular users are mainly motorists. The segment under study is a mile-long, 3% sustained gradient. PHF equals 0.88. Field research has been done to establish that the facility's free-flow speed is 55.0 miles per hour. What degree of service will be provided during peak hours at this facility?

Wrong answer will be rated negative. The horizontal distance between its PVI and PVC is 150 meter. The elevation of PVI is 450.2 meter. The initial and final grades of the road are -4% and +3% respectively. Chainage of PVC is 1620 m. Based on the given set of information, determine the followings: i. Elevation of PVC. ii. The chainage of PVI. iii. Chainage and elevation of PVT. iv. Chainage and elevation of the lowest point of the sag curve.
