The cross section notes of the ground surface at a given station of a road survey shows that the ground is sloping at an 8% grade upward to the right. The difference in elevation between the ground surface and the finished subgrade at the center line of the proposed road is 2.50 m. The width of the subgrade is 7 m with slope of 2H to 1V. 7. Find the distance of the right slope stake from the center of the road. 8. Find the distance of the left slope stake from the center of the road. 9. Find the area of the cross section. (Round off your answers to three decimal places)

Drainage of Pavements

Pavement Drainage holds ample significance, as it prevents the accumulation of water or any liquid on the surface of pavements and ensures proper drainage system. With proper design and gradual slopes provided, the water gets easily removed from the surface into the drains, which are essential during heavy rains and unusual weather conditions keeping it less prone to accidents and increasing the durability of the pavement structure.
