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.

A horizontal curve is being designed to connect two tangents that intersect on a rural collector road with a specified design volume of 2500 veh/day (i.c. design speed 60 mph). It is expected that, because of right-of-way restriction, a large billboard will be placed at a distance of 50 ft from the centerline of the inside lane. If the terrain can be described as level and only a minimal amount of snow is expected on the road, determine the minimum radius of curve. Assume maximum superelevation rate (e) of 0.1 and fs=0.12. Ans: 1090 ft
A horizontal curve is to be designed to connect two tangents on a rural principal arterial with a design speed of 110 km/h. The station of the BC is 545+13.65. It is expected that an existing building will be located at a distance of 15 m from the centerline of the inside lane. Determine the minimum radius that will satisfy the sight distance and superelevation requirements.
