A four-lane freeway (two lanes on each direction) is located on mountainous terrain with 11-ft lanes, a 5-ft right-side shoulder, and a 3-ft left-side shoulder, and a 60- mph design speed. The freeway currently operates at capacity during the peak hour. If an additional 11-ft lane is added, and all other factors stay the same, what will the new level of service be?

A: Answer:-

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.
