An underpass crossing a reinforced concrete bridge along the Shaw Blvd. has a downward grade of -4% meeting an upward grade of +8% at the vertex V at elevation 70m and stationing of 7+700, exactly underneath the centerline of the bridge having a width of 10m. If the required minimum clearance under the bridge is 5m and the elevation of the bottom of the bridge is 78.10m a. determine the length of the vertical parabolic curve that shall connect the two tangents. b. determine the stationing of the point where a catch basin will be placed. c. determine the elevation of the point where a catch basin will be placed.

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.
