Question

Why friction facor negleted for design super elevation?

Answer 1

providing lower superelevation considering coefficient of friction is safe, i.e.centrifugal force is ... Step 1 Find e for 75 percent of design speed, neglecting f, i.e e1 = (0.75v)2. gR.
i hope it will help you

Answer 2

hiii •••••here is your answer :-

Superelevation of Horizontal Curves The purpose of superelevation or “banking” of curves is to counteract the centripetal acceleration produced as a vehicle rounds a curve. Superelevation is the inclination of the roadway toward the center of the curve.
