An existing horizontal curve has a radius of 85 meters, which restricts the maximum speed on this section of road to only 60% of the design speed of the highway. Highway officials want to improve the road to eliminate this bottleneck. Assume coefficient of side friction is 0.15 and rate of superelevation is 0.08. Compute the existing speed, design speed, and find the new radius of curvature.

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.
