2. Bushes grow near a two-lane highway circular curve with R = 160 m (measuredfrom centreline of the highway). Minimum stopping sight distance is 150 m. Totalwidth of pavement is 7.0 m. How near from the edge of the pavement can you allowthe bushes to grow? (ans M=15.69m and Minimum SSD= 150m)
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.
