Extra widening formula
WebGo Extra Width = (Wheelbase+Lap of Flange^2)*125/Radius of curve Wheel Base given Extra Width Formula Wheelbase = (Extra Width*Radius of curve/125)-Lap of Flange^2 W = (We*R/125)-L^2 Why Extra Widening is provided at curves? Extra Width is the result of extra widening of the pavement at the curves. WebExtra widening on the curves of the road refers to the additional width of the carriageway that is required on a curved section of the road over and above the width required on the straight section. Why extra widening in highway required? Additional width at the horizontal curve is required due to the following reasons.
