An asphalt pavement drains into a rectangular concrete channel. The catchment surface has an average slope of 1.0%, and the distance from the catchment boundary to the drain is 30m. The drainage channel is 60 m long, 20 cm wide, 25 cm deep, and has a slope of 0.6%. For an effective rainfall rate of 50 mm/h, the flow rate in the channel is estimated to be 0.02 m³/s. Estimate the time of concentration of the catchment.

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.
