Necessity of Providing Extra Widening of Pavement on Curve
On curves, the following difficulties are observed, that why extra widening of pavement on a curve are provided:
1. On curves, the vehicles occupy a greater width because the rear wheels follow the inner path as compared to the front wheel.
2. On curves, drivers have difficulty in steering their vehicle to keep to the center line of the road.
3. Drivers have psychological fear to drive close to the edge of the pavements on curves.
Widening of pavement on a curve is necessary to compensate for the above difficulties.
