A sewer pipe must be laid from a starting invert elevation of 784.58 ft at station 9+25 to an ending invert elevation 782.48 ft at station 12 + 75. Determine the uniform grade needed, and calculate invert elevations at each 50-ft station. (elevation answers are to the nearest hundredth of a foot X.XX.

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.
