Edge of pavement

A edge of pavement is the part of the pavement in contact with the Chaussée. Typically made Concrete, or rather of long stones (often the Granite), the destination in is double: initially like gutter for the suitable drainage of the roadway, then for safety in order to prevent the motorists from leading on the pavement.

Like a gutter, he guides and snow melt rainwater in the rain drains, which prevents water from accumulating on surface. Large puddle pools can be dangerous and be the cause of the Aquaplanage and the loss of control of a car, outcome with an car accident. Even at the lower speeds, water and mud can pulverize in top of tires on the motorists of behind, causing the loss of the visibility. Finally, they can also splash the pedestrians, leaving them soaked and of bad mood.

There is also an esthetic aspect, that gives a finished aspect. Since the edges of pavement add an additional cost to the realization of the roads, they are generally limited to the urban sectors and of suburbs and are seldom found in rural sectors except where certain conditions of drainage (like the mountains or the gutters) make them necessary.

The edges of pavement can be square, tilted, or rounded. This last kind is more often used at the edge of the alleys and continuously along the residential streets of suburbs where there are many alleys and lawns. That supplemented the almost flat type starting like the road, the curves in top in a concave way with a soft slope, are curved then behind in a convex way with almost flat again, making it much easier to lead. The tilted type is more often used on main streets of suburbs and is more modern than the two others. The square type always or is almost always used in the cities. Its flat rim prevents the pedestrians from falling.

In addition to the alleys, the edges of pavement also go down inclined on the level from the pedestrian crossings and the exits from garage. It are generally elevated on the level of the bus stop giving handicapped access to the people.
