Superelevation is intended to assist the driver by counteracting the lateral acceleration produced by tracking the curve. Superelevation is expressed as a decimal, representing the ratio of the pavement slope to width, ranging from 0 to 0.12 …

Superelevation - Wikipedia

WebCurved roadway sections on higher speed roads are gener- ally constructed with superelevation to compensate for the centripetal forces exerted on the vehicles, making it easier for the driver to control the vehicle through the curved section.

WebThe superelevation is provided on the road by the following formula e + f = (V2 / 127 R) R = 0.036 V2 Where, e = rate of super elevation f = design coefficient of lateral friction= 0.15 g … WebWhere a crown section is used for rapid drainage, the shoulder slope must be steeper than that of the pavement (See the chart above), but on a pavement uniformly sloped either to the outside or the inside (such as on a super-elevated curve), the shoulder slope generally is the same as that of the pavement.

WebFor example, a superelevation rate of 10% implies that the roadway surface elevation increases by 1 ft for every 10 ft of roadway width. The side-friction factor is simply the coefficient of friction between the design vehicle's tires and the roadway.
