A grade descending at the rate of -4% intersects another grade ascending at the rate of +8% at station 2+000 and elevation 100m. A vertical curve (symmetrical) is to connect the two such that the curve will clear a boulder located at station1+980 (elevation 101.34m).  a. Determine the necessary length of the curve. b. Determine the station of the location of a sewer to be laid out. c. Compute the elevation of station where the sewer is to be place.

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.
