WebThe length of a vertical curve depends upon the algebraic difference between the gradients and the type of curve formed (summit or sag). The rate of change of gradient in the case of summits should not exceed 0. 1% between successive 30.5-m (100-ft) chords, whereas the corresponding figure for sags is 0.05% per 30.5-m (100-ft) chord. WebStreet curves should be designed with as large a radius as feasible, the minimum radius being 100 feet. Where curves are superelevated, lower values may apply, but the radius …
