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.

Question

26: In a tile drainage system, the drains are laid with the centre 1.5 below the ground level. The
impervious layer 9 m ground level and annual average rainfall in area is 80 cm if 1% of the annual
rainfall is to be drained in 24 hr to keep the highest position of water table to 1 m below the ground
level. Determine the spacing of drain pipes. K = 0.01 cm/s.
