Hair pin bend in Road

This curve is so-called because it conforms to the form of a hairpin. The band so formed at the hairpin curve during a hill road is understood as the hairpin bend.

This type of curve should be located on a hillside having the minimum slope and maximum stability. It must even be safe from the point of view of landslides and groundwater.

Hairpin bends with long arms and farther spacing are always preferred. Hey, reduce construction problems and expensive protective works. Hear-pin curves or bends of serpentine nature are difficult to barter and may, therefore, be avoided as far as possible.
