Highway-Superelevation

Methods of Attaining Superelevation: -

1. Crowned Travelled Way Revolved About Centreline

2. Crowned Travelled Way Revolved about Inside Edge

3. Crowned Travelled Way Revolved about Outside Edge

4. Straight Cross Slope Travelled Way Revolved about Outside Edge

However, there is no rule on which method to be adopted, as consideration needs to be made based on profile arrangements, drainage, avoidance of critical grades, aesthetics and fitting the roadway to the adjacent topography.
